Step-by-step explanation:

Continuation of the question:

  • 1. Find c (5) and interpret your solution in the context of the problem
  • 2. Find the value of h when c() = 525 and interpret your solution in the context of the problem

Solution

  • c(h) = 30h + 180

1 ...............................................

  • c(5) = 30*5 + 180 = $330

2 ...............................................

  • 525 = 30h + 180

  • 30h = 345
  • h = 345/30
  • h = 11.5 hours
