Geri used coupons at the grocery store and received a discount of $40.94. Once her discount was subtracted, the final cost of her purchases was $122.80. What was the approximate percent decrease in the price of her groceries due to the coupons?
Step-by-step explanation:
Price after discount = 122.80
Discount = 40.94
So, amount before discount = 122.80 + 40.94 = 163.74
[tex]decrease[/tex] [tex]in[/tex] [tex]price[/tex] = [tex]\frac{discount}{original price}[/tex] x 10
= [tex]\frac{40.94}{163.74} (100)[/tex]
= 0.25
= 0.25 x 100
= 25%
You are selling tickets for a high school basketball game. Student tickets cost $3 and general admission tickets cost $5. You sell 350 tickets and collect $1450. How many of each type of ticket did you sell?
Answer:
5 stars? Answer down below
Step-by-step explanation:
a+b=350 => a=350 - b
3a + 5b = 1450
3(350-b)+b=1450
1050-3b+5b=1450
2b=400
b=200
a=150
There are 200 student ticket and 150 general admission ticket sold.
What is selling price?The selling price is used to sell the item at a certain cost and can be calculated using the selling price formula. The amount that the buyer pays to buy the product is called the selling price.
Here,
We sold some number, x, of $5 tickets and some number, y, of $3 tickets. If we sold 350 tickets total then x + y = 350. If we made $1450 total on ticket sales, then the sum of y tickets at $3 plus x tickets at $5 needs to equal $1450.
So,
$3y + $5x = $1450
and x + y = 350
Solve system of equations.
3(350-x) + 5x = 1450
1050 -3x + 5x = 1450
2x = 400
x=200
y + 200 = 350
y=150
Thus, there are 200 student ticket and 150 general admission ticket sold.

Jerry has a new job and earns a salary of $45,000. Victoria has a new job and earns a salary of $54,000. Jerry will receive a salary increase of $2,500 per year, and Victoria will receive a salary increase of $1,500 per year. Which equation can be used to find x, the number of years it will take Jerry to earn the same salary as Victoria?
A.) 45,000x + 2,500x = 54,000x + 1,500x

square root of 9
-0.25
pi
0.6 (the six has a line over it)
Answer:
3^-1, square root of 9, -0.25, and 0.6
Step-by-step explanation:
Rational numbers are numbers that you can turn into fractions.
3^-1 = 0.3333333333... which is also known as 1/3
square root of 9 = 3, which can be written as 3/1
-0.25 can be written as -1/4
0.66666666... = 2/3
The numbers 3⁻¹ , sqrt(9), -0.25 and 0.6 are the rational numbers.
What is Number system?A number system is defined as a system of writing to express numbers.
The rational numbers are those that can be expressed as a ratio of two integers.
3⁻¹ = 1/3, which is a rational number.
sqrt(12) = sqrt(4 x 3) = 2sqrt(3), which is irrational.
sqrt(9) = 3, which is a rational number.
-0.25 = -1/4, which is a rational number.
pi is irrational.
0.6 = 3/5, which is a rational number.
Hence, 3⁻¹ , sqrt(9), -0.25 and 0.6 are the rational numbers.
