Question

The cost in dollars to produce x shovels in a factory is given by the function C(x)=20x+410. The number of shovels that can be produced in h hours is given by the function N(h)=30h.

1. find the rule for C(n(h))
2. Find the cost when h= 12 hours

please help asap!

Answer 1

Cost when h=12 hours will be 7610

C(x)=20x+410

N(h)=30h

C(N(h))= 20 * 30h + 410

C(N(h))= 600h + 410

Cost when h=12,

600*12+410=7610
