Question

Market and More is having a cereal sale. Every box of cereal is 5050 off the regular price.

Jane has $10 and she wants to buy 4 boxes of the same cereal. Solve the inequality below to determine the regular price of cereal that she can afford. 4(r - 0.6) ≤ 10, where r = regular price. Show your work.

Answer 1

10 >= 4(r-.60)

Explanation:

Let r be the regular price of a box of cereal

The sale price is .60 off

New price is r-.60

She wants to buy 4 boxes, so multiply the new price by 4

4(r-.60)

She only has 10 dollars so the price must be less than or equal to 10 dollars

10 >= 4(r-.60)
