Answer: 3.75
Step-by-step explanation:
First, write an equation to solve your problem:
20x + 100 = $175
20x equals the $20 per hour fee, $100 represents the rental fee and $175 is the amount of money that you have.
First, subtract 100 from each side:
20x = 75
Next, divide both sides by 20:
X = 3.75
