Question

a cleaning company charges a flat fee of $8 and $30 per hour to clean a home. write an equation that can represent the situation if each represents the number of hours and a customer pays a total of $128 for cleaning services

Answer 1

In order to reach the total cost of $128, you need to find the number of hours the company cleaned. The equation to do so would be
 
  30x+ 8 = 128

If you subtract 8 from both sides and then divide by 30 you'll find that x=4.
