A mail courier charges a base fee of $4.95 plus $11.90 per package being delivered. If x represents the number of packages delivered, which of the following equations could be used to find y, the total cost of mailing packages?
Set up the cost function y = C(x)
C(x) = 4.95 + 11.90x
Set up the cost function y = C(x)
C(x) = 4.95 + 11.90x
