5 boys shared the cost of a present equally. When calculating the amount each boy had to pay, a mistake was made. The cost of the present was divided by 6 instead of 5. Each boy ended up paying $2.70 less than the correct amount. What should be the correct amount for each share?

5 boys |
6 boys |
| Number |
5 |
6 |
| Value |
1 u + 2.70 |
1 u |
| Total value |
5 u + 13.50 |
6 u |
Total cost of the present if it was paid by 5 boys
= 5(1 u + 2.70)
= 5 u + 13.50
Total cost of the present if it was paid by 6 boys = 6 u
6 u = 5 u + 13.50
6 u - 5 u = 13.50
1 u = 13.50
Correct amount for each share
= 1 u + 2.70
= 13.50 + 2.70
= $16.20
Answer(s): $16.20
