A store sells jump ropes. Each jump rope costs the same amount. During a sale, the store reduces the price of each jump rope by $1.80. Gavin spends $14.38 on 2 jump ropes at the sale price.
What was the price of 1 jump rope before the sale? Enter the answer in the box.

Work Shown:

x = price of one jump rope before the discount

x-1.80 = price of one jump rope after discount

2*(x-1.80) = total amount Gavin spends

2*(x - 1.80) = 14.38

x - 1.80 = 14.38/2 divide both sides by 2

x - 1.80 = 7.19

x = 7.19 + 1.80 adding 1.80 to both sides

x = 8.99

Before the sale, one jump rope costs 8.99 dollars

After the sale, one jump rope costs 8.99 - 1.80 = 7.19 dollars.

This doubles to 2*7.19 = 14.38 dollars which is what Gavin spent in total. This helps confirm the answer.

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
