A piano manufacture has a daily fixed cost of $1,000 and a marginal cost of $1,500 per piano. Find the cost C of manufacturing x pianos in one day.
A) $C ( x ) = 1,500 x - 1,000$ per day
B) $C ( x ) = 1,000 x - 1,500$ per day
C) $C ( x ) = 1,500 x$ per day
D) $C ( x ) = 1,000 x + 1,500$ per day
E) $C ( x ) = 1,500 x + 1,000$ per day

A) $C ( x ) = 1,500 x - 1,000$ per day
B) $C ( x ) = 1,000 x - 1,500$ per day
C) $C ( x ) = 1,500 x$ per day
D) $C ( x ) = 1,000 x + 1,500$ per day
E) $C ( x ) = 1,500 x + 1,000$ per day

Quizplus · Accepted Answer

The cost of manufacturing x pianos in one day includes the daily fixed cost of $1,000 plus the marginal cost of $1,500 per piano, which gives $C(x) = 1,500x + 1,000$.

A Piano Manufacture Has a Daily Fixed Cost of $1,000 C(x)=1,500x−1,000C ( x ) = 1,500 x - 1,000C(x)=1,500x−1,000

A Piano Manufacture Has a Daily Fixed Cost of $1,000 $C ( x ) = 1,500 x - 1,000$
