Question

Tina has a pet sitting business. She charges a flat service fee of $20, plus $15 per day for each animal. If one of her customersspent less than $110 on one animal, which of the following inequalities could be used to solve for x, the number of days thecustomer paid for pet sitting?

Answer 1

If the initial fee is $20 and additionally $15 is charged per day, then the total amount is given by:

`A=20+15x`

Where "x" is the number of days and "A" the total amount to pay. Since the total amount is less than $110, then we have the following inequality:

`20+15x\le110`

This is the inequality that can be used to determine the value of "x".
