$9.30 more |
Amount that his friend spent on 5 cups
= 5 x 5.10
= $25.50
Let the cost of 1 mug be 1 M.
If Fabian's friend spent $9.30 less, each would pay the same amount.
8 M + 9.30 = 6 M + 25.50 - 9.30
8 M - 6 M = 25.50 - 9.30
2 M = 16.20
1 M = 16.20 ÷ 2 = 8.10
Total amount that Fabian and his friend spent
= 8 M + 6 M + 25.50
= 14 M + 25.50
= 14 x 8.10 + 25.50
= 113.40 + 25.50
= $138.90
Answer(s): $138.90
