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£
