Question 909554: Piecewise Function: Suppose a car rental company charges $88 for the first day & $38 for each additional or partial day. let S(x) represent the cost of renting a car for x days. Find the Value of S(4.5).

I have tried S(x)={88 if x<= 1 or 88+38(x) x>1
S(4.5)=88+38(4.5)
88+171=259
The Answer is suppose to be $240

You can put this solution on YOUR website!
s=88+38x
You will charged for at least one day or nothing (because you didn't rent a car at all)
S(4.5)=88+38(4.5-1)x
4.5 days is the same as 5 days
S(5)=88+38(5-1)
S(5)=88+38(4)
