Answer 1

Complete question :

You can spend up to $35 on a shopping trip.

a. You want to buy a shirt that costs $14. Write and solve an inequality that represents the amount of money you will have left if you buy the shirt.

b. You notice that the shirt is on sale for %30 off. How does this change the inequality?

c. Do you have enough money to buy the shirt that is on sale and a pair of pants that cost $23? Explain.

Answer:

x ≤ 21

x ≤ 25.2

Yes

Step-by-step explanation:

Cost of shirt = $14

Total Amount to spend ≤ $35

After shirt purchase :

Let amount left = x

x + 14 ≤ 35

x ≤ 35 - 14

x ≤ $21

B.) discount on shirt sale = 30%

(100% - 30%) of $14 = 0.7 * $14 = $9.8

x ≤ 35 - 9.8

x ≤ 25.2

C.)

Cost of Jean = 23

25.2 > 23

Hence, there is enough money
