Question

If the function C(x) = 8x represents a cost function for selling LHS laser engraved plaques, then what is the cost when selling 18 plaques?

A) 8
B) 16
C) 72
D) 144

Answer 1

The cost of selling 18 LHS laser engraved plaques, represented by the cost function C(x) = 8x, is $144.

Step-by-step explanation:

The cost function for selling LHS laser engraved plaques is given by the equation C(x) = 8x. To find the cost of selling 18 plaques, you simply substitute x with 18 into the cost equation:

C(18) = 8(18) = 144

Therefore, the cost when selling 18 plaques is $144.
