There was a flat fee of 10 dollars

Each 1/4 hour brought in 3,75

The total charge was 55 dollars.

Equation

Charge = 10 + 4*3.75*x as an hourly rate,

Solution

55 = 10 + 4*3.75x Combine

55 = 10 + 15x Subtract 10 from both sides

55-10= 10-10 + 15x

45 = 15x Divide by 15

45/15 = 15x/15

x = 3 hours

Answer 3 hours
