8. How much does it cost to rent the jet-ski for 5 hours?
A.125 B.225 C.385 D.525
I tried:
f(x)=25x+100
f(x)=25(5)+100
F(x)=225+100
f(x)=325
THANK YOU

You can put this solution on YOUR website!
It was an arithmetic error:
f(x)=25x+100
f(x)=25(5)+100
F(x)=225+100 <- should be f(x) = 125 + 100
f(x)=325 <- should be 225
