Question

Roopesh has $24 dollars to spend on a birthday gift. The store where he is shopping has a sale offering $5 off the regular price, r, of any item. Write an inequality that can be used to determine the regular price of an item in the store that Roopesh can afford. (Assume there is no tax.)

What is the unknown?



Which expression can represent the sale price?



Which comparison could be used?



Which inequality represents the situation?

Answer 1

r ≤ 29, r-5, The sale price can be compared with the regular price, r-5 ≤ 24

Explanation:

• Amount to spend = $24
• Regular price = r
• Sale = $5
• Sale Price = r-5

The regular price will be at most $5 more than the amount Roopesh has to spend.

The sale price will be $24 or less than that for Roopesh to afford.

Inequality for regular price :

r-5 ≤ 24

r ≤ 29

Therefore, the product Roopesh can afford is $29 or less than that.

1. What is the unknown? r ≤ 29
2. Which expression can represent the sale price? Sale price = r-5 (mentioned above)
3. Which comparison could be used? The sale price can be compared with the regular price
4. Which inequality represents the situation? r-5 ≤ 24
