Question

• the total cost of the materials is $880.
• three workers, working simultaneously, each charge $15 per hour.
• each landscaper works for h hours.

complete the equation for function c.

Explanation:

Step1: Identify fixed and variable costs

Fixed cost (materials) = $880. Variable cost: 3 workers, each $15 per hour for \( h \) hours. So variable cost = \( 3 \times 15 \times h = 45h \).

Step2: Formulate total cost function

Total cost \( C \) is fixed cost plus variable cost. Thus, \( C = 45h + 880 \).

Answer:

\( C(h) = 45h + 880 \)
