To determine

To find: We are asked to write and solve an inequality to find possible amounts the family can save each month.

Answer to Problem 22P

The possible amount the family can save as $550 or less.

Explanation of Solution

Given information: A family earns $1800 per month. The family expenses are minimum $1250.

Calculation:

We know saving is earning- expense.

Let savings is ‘$ x’

We can rewrite it as $saving+expense$ is earning

Here it is given earning is $1800, expense is minimum $1250.

So, we can set up inequality as $x+1250\le 1800$

Let’s solve the inequality by subtracting both sides 1250.

  $x\le 550$
