Answer:

  • 4 hours

Step-by-step explanation:

The equation to show the total charge:

  • c(h) = 15 + 8.5h, where h is the number of hours

Substitute 49 into equation and solve for h:

  • 15 + 8.5h = 49
  • 8.5h = 34
  • h = 34/8.5
  • h = 4

Let no of yours be x

The equation is

  • y=8.5h+15

Put y=49

  • 49=8.5h+15
  • 8.5h=34
  • h=4hours
