Answer:

  • 5 hours

Step-by-step explanation:

Let the hours of actual work be x and total charge be y.

The greenhouse

Total amount of charge is:

  • y = 11x + 20

Garden pros

Total amount of charge is:

  • y = 15x

Since y is same for both companies, set the equation and solve for x:

  • 11x + 20 = 15x
  • 15x - 11x = 20
  • 4x = 20
  • x = 20/4
  • x = 5
