In a sale, a shopkeeper reduced the advertised selling price of a dress by 20%. This resulted in a profit of 4% over the cost price of the dress. What percentage profit would the shopkeeper have made if the dress had then been sold at the original selling price?
HELP my dad will kill me if I don't finish this and I'm stuck on this question
Answer:
30% profit
Step-by-step explanation:
The amount by which the shopkeeper reduced the advertised selling price = 20%
The resulting profit over the cost price = 4%
Let x represent the initial advertised selling price, and let y represent the new selling price, and let c represent the cost price, we have;
x - 20% of x = y
x - x × 20/100 = y
0.8·x = y
y = c + 4% of c = 1.04·c
∴ 0.8·x = 1.04·c
x = 1.04·c/0.8 = 1.3·c
x = 1.3·c = c + 0.3·c = c + 30% of c
x = c + 30% of c
From which we have that the initial advertised selling price, x = The cost price + 30% of the cost price
Therefore, the initial advertised selling price = The cost price + 30%profit on cost price.
The shopkeeper would have made 30% profit if the dress had then been sold at the original selling price.

Heidi's friends want to reserve a karaoke studio this weekend. It cost $30 to reserve a room, plus $5 per person for pizza, plus $2 per person for a soda. How many people can be in the group if the total cost is $65 please this is the last 2 questions I have
Answer:
5
Step-by-step explanation
2 + 5 is 7 which equals 1 person 7 x 5 = 35 which means their will be 5 people per group because 30 {room cost} plus 35 is 65
what do i mean?
2 + 5 IS 1 person and 2 plus 5 is 7 so the remaining money they have would be 35 because 65 minus 30 is 35 so i divid 35 by 7 which brings 5 people

Solve the system of equations 2x-y= 13x and -3x+2y=-18 by combining the equations.
Answer:
x = 18/25, y = -198/25
Step-by-step explanation:
Given the system of equations:
2x – y = 13x
-3x + 2y= -18
You can combine these two equations effectively by multiplying the first equation by 2, and adding because -2y and 2y will cancel out when added. So you will be left with only x terms
( 2x - y = 13x ) × 2
+ -3x + 2y = -18
________________
2(2x) - 3x + 2(-y) + 2y = 2(13x) - 18
4x - 3x - 2y + 2y = 26x - 18
x + 0 = 26x - 18
x = 26x - 18
________________
[Then use the properties of equality to simplify the expressions in the equation to derive the value of x]
x - x = 26x - 18 - x (subtraction property of equality)
0 = 25x - 18
0 + 18 = 25x - 18 + 18 (addition property of equality)
18 = 25x
18 / 25 = 25x / 25 (division property of equality)
18 / 25 = x
x = 18 / 25 (symmetric property of equality)
_______________
Now with the value of x, we can find the value of y by substituting the value of x into the variables of the top equation {2x – y = 13x} because this involves the simpliest steps.
Given x = 18 / 25.
2x – y = 13x → 2x – y + y = 13x + y → 2x = 13x + y → 2x – 13x = 13x + y – 13x → -11x = y → y = -11x.
Now that we know y = -11x, y = -11(18/25) which is - (11 × 18) / 25 = -198/25
marco needs to buy some cat food. At the nearest store, 3 bags of cat food cost 13.50. How much would Marco spend on 5 bags of cat food
Answer:
$22.50
Step-by-step explanation:
if 3 bags of cat food = 13.50, divide 13.5 by 3 to get the cost of one bag, which is $4.50.
since hes getting 5, we can use 13.50 once and then the price of one bag (4.5) twice for the other two.
so that would be 13.5 + 4.5 + 4.5 = $22.50
hope this helped :)
Answer:
cost of three bags of cat food = 13.50
cost of 1 cat food = 13.50/3 = 4.50
cost of 5 cat food = 4.50*5 = 22.5

Which expression is equivalent to Negative 2 and one-fourth divided by negative two-thirds?
StartFraction 9 over 4 EndFraction divided by three-halves
Negative StartFraction 9 over 4 EndFraction divided by (negative two-thirds)
Negative StartFraction 9 over 4 EndFraction divided by two-thirds
StartFraction 9 over 4 EndFraction divided by (negative three-halves)
Answer:
ITS B !!!!!!!!!!!!!
Step-by-step explanation:
The equivalent expression is -9/4 ÷ (-2/3).
Option B is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Negative 2 and one-fourth divided by negative two-thirds.
This can be written as,
-2(1/4) ÷ (-2/3)
= -9/4 ÷ (-2/3)
= -9/4 x -3/2
= 27/8 _____(A)
Now,
StartFraction 9 over 4 EndFraction divided by three-halves
This can be written as,
9/4 ÷ 3(1/2)
= 9/4 x 2/7
= 18/28 ______(1)
Negative StartFraction 9 over 4 EndFraction divided by (negative two-thirds)
This can be written as,
-9/4 ÷ (-2/3)
= -9/4 x -3/2
= 27/8 ______(2)
Negative StartFraction 9 over 4 EndFraction divided by two-thirds
This can be written as,
-9/4 ÷ 2/3
= -9/4 x 3/2
= -27/8
StartFraction 9 over 4 EndFraction divided by (negative three-halves)
This can be written as,
9/4 ÷ -3(1/2)
= 9/4 x 2/7
= 18/28
Thus,
From (A) and (2),
-9/4 ÷ (-2/3) is the equivalent expression.

Find the value of x and the measure of side EF.
Answer:
x=5
EF = 22in.
Step-by-step explanation:
We know EF and DE are equal, so we can solve for x.
5x-3=3x+7
5x-3x=7+3
2x=10
x=5
Now we plug that into EF.
EF = 3x+7 = 3(5)+7 = 15+7=22

It is possible to have complementary angles where one is acute and one is obtuse.
Explain why or why not.
Answer:
A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. The side opposite the obtuse angle in the triangle is the longest.
