Question

You can spend up to $35 on a shopping trip. You want to buy a shirt that cost $14. Write and solve an inequality that represents the amount of money you will have left if you buy the shirt

Answer 1

Explanation:

a. 35 greater than or equal to 14 + x

35 - 14 = 21

x = $21

b. If the shirt is 30% off it would cost $9.80

14 x 0.3 = 4.2

14 - 4.2 = 9.8

35 is greater than or equal to 9.80 + x

35 - 9.8 = 25.2

x = $25.20

This changes the inequality by making x greater than it was in part a

c. Yes, you do have enough money to buy the shirt that is on sale and a pair of pants. x is the amount that you have left to spend after you buy the shirt that is on sale. 25.20 is greater than the cost of the pants.
