Ateam 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. what is the best interpretation of 155 in the equation? c = 290 + 155h a. the total cost can be at most $155. b. it takes the team 155 hours to paint the exterior. c. each additional hour of painting the exterior costs $155. d. $155 is the base cost regardless of how many hours it takes to paint the exterior.

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.

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)
