The daily cost of hiring a plumber, y, to work x hours on a repair project can be modeled using a linear function. The plumber charges a fixed cost of $80 plus an additional cost of $45 per hour. The plumber works a maximum

of 8 hours per day.

For one day of work, what is the range of the function for this situation

A. 0 ≤ x ≤ 8

B .80 ≤ y ≤ 440

C .0 ≤ x ≤ 10

D .45 ≤ y
