5 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 6 instead of 5. Each girl ended up paying $2.90 less than the correct amount. What should be the correct amount for each share?

5 girls |
6 girls |
Number |
5 |
6 |
Value |
1 u + 2.90 |
1 u |
Total value |
5 u + 14.50 |
6 u |
Total cost of the gift if it was paid by 5 girls
= 5(1 u + 2.90)
= 5 u + 14.50
Total cost of the gift if it was paid by 6 girls = 6 u
6 u = 5 u + 14.50
6 u - 5 u = 14.50
1 u = 14.50
Correct amount for each share
= 1 u + 2.90
= 14.50 + 2.90
= $17.40
Answer(s): $17.40
