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.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
