Question

A bottle manufacturer has determined that the cost (C) in dollars of producing x bottles is C=0.65x+1800

. What is the cost of producing 400
bottles?

Answer 1

Since x represents the amount of bottles, replace x in the equation with 400. This will give you the equation C=0.65(400)+1800

Multiply 0.65 by 400 to get 260
Then add 1800 to 260 to get 2060 which is your answer

C=2060
