$9.60 more |
Amount that his aunt spent on 5 glasses
= 5 x 5.70
= $28.50
Let the cost of 1 bowl be 1 B.
If Bryan's aunt spent $9.60 less, each would pay the same amount.
11 B + 9.60 = 8 B + 28.50 - 9.60
11 B - 8 B = 28.50 - 9.60
3 B = 18.90
1 B = 18.90 ÷ 3 = 6.30
Total amount that Bryan and his aunt spent
= 11 B + 8 B + 28.50
= 19 B + 28.50
= 19 x 6.30 + 28.50
= 119.70 + 28.50
= $148.20
Answer(s): $148.20
