C
each additional hour would cost 155 and the 290 is the upfront cost

Answer:

Option C

Step-by-step explanation:

Given that a team of painters is hired to paint the exterior of a museum. The total cost, C, in dollars, incurred by the museum for h hours of painting is given by the equation below.

[tex]C(x) = 290+155h[/tex]

This implies that 290 is the fixed cost incurred even if 0 hour is worked and for every additional hour 155 will be charged extra.

Total cost = fixed cost + 155 (no of hours) is the correct interpretation

Hence we get

Option C is right.

[A is wrong since for 1 hr we get >155 cost.  B is wrong since 155 is not number of hours. D is wrong because 155 is increasing for extra 1 hour)
