The one day cost of renting a truck for a local move is a function of the number of miles put on the truck. The cost c in dollars is determined from the mileage m by the linear function C(m) = 0.42m + 39. Find the cost for 66 miles.

C(66)=0.42(66)+39

C(66)=ll.72

To find the cost for 66 miles, we can use the linear function provided: C(m) = 0.42m + 39.

We substitute the value of m, which is 66, into the equation:

C(66) = 0.42(66) + 39

Next, we simplify:

C(66) = 27.72 + 39

C(66) = 66.72

Therefore, the cost for 66 miles is $66.72.
