Question

The number of motorcycle helmets produced in a factory each day is a function of the
number of hours (h) the assembly line is in operation that day and is given by n =
P(t) =
75t-2t^2. The cost C of producing the helmets is a function of C(n) = 7n + 1000

Answer 1

Answer:

C(t)=525t-14t²+1000

Step-by-step explanation:

n =P(t) =75t-2t²

C(n) = 7n + 1000

(sub in 75t-2t² for n)

C(t)=7(75t-2t²)+1000

C(t)=525t-14t²+1000
