The cost to rent a bike for 1 person under age five is 3£ and 5.50£ for anybody over age five. Calculate the cost to rent 7 bikes if 4 people are under age five and 3 people are over age five.

Solution

Total for those who are under age five

4 under age five = 4 x 3£ or 3£+3£+3£+3£

3+3+3+3 = 12

4 under age five = 12.00£


Total for those who are over age five

3 x 5.50£ or 5.50 + 5.50 + 5.50

1
5.50
5.50
5.50
-------
16.50


The two added together = the total amount

16.50
12.00
--------
28.50


The answer is 28.50£
