Based on the information given, the number of bills will have to be between 13 and 28 every month.

<h3>Solving equations</h3>

Let the number of bills be represented by x.

Therefore, the equation to solve the question will be:

2.25 + (0.10 × x) = 3.50

2.25 + 0.10x = 3.50

0.10x = 3.50 - 2.25

0.10x = 1.25

x = 1.25/0.10 = 12.5 = 13

Also, 2.25 + 0.10x = 5.00

0.10x = 5.00 - 2.25

0.10x = 2.75

x = 27.5 = 28

Therefore, the number of bills will be between 13 and 28 every month.
