5 friends shared the cost of a gift equally. When calculating the amount each friend had to pay, a mistake was made. The cost of the gift was divided by 6 instead of 5. Each friend ended up paying $3.10 less than the correct amount. What should be the correct amount for each share?

5 friends |
6 friends |
Number |
5 |
6 |
Value |
1 u + 3.10 |
1 u |
Total value |
5 u + 15.50 |
6 u |
Total cost of the gift if it was paid by 5 friends
= 5(1 u + 3.10)
= 5 u + 15.50
Total cost of the gift if it was paid by 6 friends = 6 u
6 u = 5 u + 15.50
6 u - 5 u = 15.50
1 u = 15.50
Correct amount for each share
= 1 u + 3.10
= 15.50 + 3.10
= $18.60
Answer(s): $18.60
