Tilly is going on a school trip to the zoo.
The prices are shown below:
Adult – £24.50
Child- £16.25
One adult is free with every 5 children.
In the group there are 48 children.
The total price for the group is £927.
How many adults are in the group?
Answer:
48 children cost:
48 x £16.25 = £780
Total spent on adults:
£927 – £780 = £147
£147 / £24.50 = 6 adults
Total free adults
48 / 5 = 9.6
Therefore, there are 9 free adults
Total number of adults = 9 + 6 = 15
Answer = 15 adults
