(D) P(h) = 78h – 160
(E) P(h) = –160h + 78

His fixed cost = \$150
P(h)= earnings - cost(fixed + variable)
P(h)=78h - (150 + 10h)
p(h)=68h-150

(D) P(h) = 78h – 160
(E) P(h) = –160h + 78

The daily revenue will be 78h dollars, and the daily cost is (150 + 10h) dollars. Therefore, the daily profit is P(h) = 78h - (150 + 10h) = 68h - 150 dollars.
