Question

Someone tell me the answer please

Answer 1

Explanation:

Cost = 45 * hours worked (x) + 60

a) Cost = 45 * 2 + 60

90 + 60 = 150

b) Cost = 45 * x + 60

285 = 45x + 60

- 60 -60

225 = 45x

/45 /45

5 = x

The job lasted 5 hours.

c) 60 represents the cost for hiring an electrician for 0 hours.

Hope that helps!
