The cost to manufacture x pairs of sunglasses can be represented by a function C(x). If it costs $398 to manufacture 4 pairs of sunglasses, which of the following is true?

A.) C(4) = 99.50

B.) C(398) = 4

C.) C(4) = 398

D.) C(99.50) = 1

A.) C(4) = 99.50

B.) C(398) = 4

C.) C(4) = 398

D.) C(99.50) = 1

**The cost of manufacturing 4 pairs of sunglasses is $398**

cost of 4 is 398

In function notation, that is:

C(4) = 398

**C.) C(4) = 398**
