Question
Using f of x to represent the total cost, and x to represent the number of hours, which function models this situation?

Answer options with 4 options
A.
f of x equals 190 x plus 90

B.
f of x equals 100 x plus 90

C.
f of x equals 90 x plus 190

D.
f of x equals 90 x plus 100

Answer 1

The correct function that represents this situation is:

C. f(x) = 90x + 190

This function represents the linear relationship between the number of hours (x) and the total cost (f(x)). The slope is 90, representing the cost per hour, and the y-intercept is 190, representing the base cost.
