Question

teks 7.11a: write a two - step equation to model the following: a plumber charges a flat fee of $50 plus $35 per hour (h). the total cost (c) was $155.

Explanation:

Step1: Identify fixed and variable costs

Fixed fee: $50, variable cost: $35 per hour (\(h\)), total cost \(C = 155\).

Step2: Formulate the equation

Total cost = fixed fee + (hourly rate × hours). So, \(50 + 35h = 155\).

Answer:

\(50 + 35h = 155\)
