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?

Answers

Step-by-step explanation:

Price after discount = 122.80

Discount = 40.94

So, amount before discount = 122.80 + 40.94 = 163.74

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?

Answers

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.

Answer:

It’s b.

Step-by-step explanation:

To get the slope of the line, you need to points. Two points you already have are (0,0) and (-5,6). So all you need to do is plug those points into slope equation (y1-y2 over x1-x2) 0-6 over 0+5 equals -6/5. The slope equals -6/5, and when you plug it into y=mx+b it equals y=-6/5x. Which is b.

Answers

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.
