4 girls shared the cost of a gift equally. When calculating the amount each girl had to pay, a mistake was made. The cost of the gift was divided by 5 instead of 4. Each girl ended up paying $3.10 less than the correct amount. What should be the correct amount for each share?

4 girls |
5 girls |
| Number |
4 |
5 |
| Value |
1 u + 3.10 |
1 u |
| Total value |
4 u + 12.40 |
5 u |
Total cost of the gift if it was paid by 4 girls
= 4(1 u + 3.10)
= 4 u + 12.40
Total cost of the gift if it was paid by 5 girls = 5 u
5 u = 4 u + 12.40
5 u - 4 u = 12.40
1 u = 12.40
Correct amount for each share
= 1 u + 3.10
= 12.40 + 3.10
= $15.50
Answer(s): $15.50
