A manufacturer keeps track of her monthly costs by using a "cost function" that assigns a total cost for a given number of manufactured items, x. The function is C (x) = 1,500 + 3x. Answer the following questions.

How much would 2,000 items

2000 items cost $ 7500

Solution:

Given that,

The function is:

C (x) = 1500 + 3x

Where,

C (x) is the total cost

"x" is the number of manufactured items

How much would 2,000 items cost

Substitute x = 2000 in given function

C (2000) = 1500 + 3 (2000)

C (2000) = 1500 + 6000

C (2000) = 7500

Thus 2000 items cost $ 7500
