It costs $45 to rent a car each day. there is also a fee of $12. how much does it cost to rent a car for 5 days, including the fee?

So, your saying that it cost $45 to rent a car AND a $12 fee.

$45+12=$57

Since your renting it for 5 days, you will have to multiply 57 and 5.

 $57x5=285

$285 is your answer. (If you have daily fees)

If the fee isn't daily, then you put ($45x5)+12=n, if the fee isn't daily

$45x5=225
225+12=237
$237 is your answer if you don't have daily fees.

45+12=57
57*5=285

I hope this helped in some way
