Formulate a function rule for the total cost C(x)

Question

Elaine broke stereotyping by becoming an auto mechanic. For home services, she charges a base fee of

₱500.00 for each visit and ₱360.00 per hour of her labor. Formulate a function rule for the total cost

C(x) for a home visit and x hours of labor. If she worked for two and a half hours fixing Samantha’s car,

how much did Samantha pay her?

Answer 1

C(x) = 500 + 360x

C(2.5) = 500 + 360(2.5) = 500 + 900 = 1,400

C(2.5) = 1,400

Unless Samatha brought the car to Elaine and there was no "home visit" then the cost would be 900.
