3 children shared the cost of a gift equally. When calculating the amount each child had to pay, a mistake was made. The cost of the gift was divided by 4 instead of 3. Each child ended up paying $3.20 less than the correct amount. What should be the correct amount for each share?

3 children |
4 children |
| Number |
3 |
4 |
| Value |
1 u + 3.20 |
1 u |
| Total value |
3 u + 9.60 |
4 u |
Total cost of the gift if it was paid by 3 children
= 3(1 u + 3.20)
= 3 u + 9.60
Total cost of the gift if it was paid by 4 children = 4 u
4 u = 3 u + 9.60
4 u - 3 u = 9.60
1 u = 9.60
Correct amount for each share
= 1 u + 3.20
= 9.60 + 3.20
= $12.80
Answer(s): $12.80
