You would divide the new bikes by four to find out the amount of used bikes
so 15
You would owe the rental shop 54 dollars
13.00 x 5.00 = 18.00
since it is per hour you multiply 18.00 x 3
3 stands for the hours you kayaked
and that gives you 54
therefore your answer is 54<span />
4 divided by 6 times 5 equals 3.333
