Hey there,

Your question states: <span>To rent a midsize car for one day, Speedy charges a flat rate of $41 plus an additional fee of $0.10 per mile driven. Use your function from the previous question, to predict the total cost of renting a car for one day, given that you plan to drive the car 200 miles.

.10/200

20+41= 61

61 would be your correct answer.

Hope this helps.

Evaluate f(x)= -2x for x=3
cluponka [151]
Replace all x's with the value of x.

f(x) = -2x becomes f(3) = -2(3)

f(3) = -2(3)
f(3) = -6

So, -6 is the answer.
