Write the function rule
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?
Select the correct equation.
A.) C(4) = 99.50
B.) C(398) = 4
C.) C(4) = 398
D.) C(99.50) = 1
The cost, C, is dependent upon the number of sunglasses made, x.
Number of sunglasses, x, is the input, while cost, C, is the output.
C.) C(4) = 398 is the correct equation
The cost is $398 to manufacture 4 pairs of sunglasses.
