Question

Alice and Betty each want to buy the same kind of ruler. But Alice is 22 cents short and Betty is 3 cents short. When they combine their money they still do not have enough money. What is the most the ruler could cost?

Answer 1

Answer:

The rule could cost 24 cents at most.

Step-by-step explanation:

Let x cents be the price of the ruler.

Alice is 22 cents short, so Alice has x - 22 cents.

Betty is 3 cents short, so Betty has x - 3 cents.

When they combine their money they have

x - 22 + x - 3 = 2x - 25 cents.

This amount is still not enough, so

$2x-25$

Solve this inequality:

$2x-x$

The rule could cost 24 cents at most.
