The cost of a truck rental for a day is $45.00, plus an additional $0.25 for every mile driven.
Which function gives the cost of the daily truck rental?
Responses
A f(x) = 0.25 + 45f(x) = 0.25 + 45
B f(x) = 0.25 + 45xf(x) = 0.25 + 45x
C f(x) = 0.25x + 45f(x) = 0.25x + 45
D f(x) = 0.25x + 45x
C f(x) = 0.25x + 45
The correct function that gives the cost of the daily truck rental is option C: f(x) = 0.25x + 45.
The cost of a truck rental for a day consists of a fixed fee of $45.00 plus an additional charge of $0.25 for every mile driven. To express this information as a function, we can use the variable x to represent the number of miles driven.
Since the additional charge is based on the number of miles driven, it should be multiplied by x. Therefore, the function that gives the cost of the daily truck rental is f(x) = 0.25x + 45.
So, the correct answer is C: f(x) = 0.25x + 45.
