Question

Finance A bicycle shop hires road bikes for £25 per day and tandems for £40 per day. One day a family pays £155.

a Which type of bicycles did they hire?
b How many people are in the family?

Answer 1

3 road bikes and 2 tandems

7 people

Explanation:

25b + 40t = 155

b=3 and t = 2

Check

25*3 + 40*2 = 155

75+80 = 155

Assuming 1 person per road bike and 2 people per tandem

3*1 + 2*2 = 3+4 = 7
