3 boys shared the cost of a souvenir equally. When calculating the amount each boy had to pay, a mistake was made. The cost of the souvenir was divided by 4 instead of 3. Each boy ended up paying $3.80 less than the correct amount. What should be the correct amount for each share?

3 boys |
4 boys |
| Number |
3 |
4 |
| Value |
1 u + 3.80 |
1 u |
| Total value |
3 u + 11.40 |
4 u |
Total cost of the souvenir if it was paid by 3 boys
= 3(1 u + 3.80)
= 3 u + 11.40
Total cost of the souvenir if it was paid by 4 boys = 4 u
4 u = 3 u + 11.40
4 u - 3 u = 11.40
1 u = 11.40
Correct amount for each share
= 1 u + 3.80
= 11.40 + 3.80
= $15.20
Answer(s): $15.20
