6 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 7 instead of 6. Each child ended up paying $1.80 less than the correct amount. What should be the correct amount for each share?

6 children |
7 children |
Number |
6 |
7 |
Value |
1 u + 1.80 |
1 u |
Total value |
6 u + 10.80 |
7 u |
Total cost of the gift if it was paid by 6 children
= 6(1 u + 1.80)
= 6 u + 10.80
Total cost of the gift if it was paid by 7 children = 7 u
7 u = 6 u + 10.80
7 u - 6 u = 10.80
1 u = 10.80
Correct amount for each share
= 1 u + 1.80
= 10.80 + 1.80
= $12.60
Answer(s): $12.60
