7 bowls + 5 cups = 7 bowls + 33.50 |

$16.40 more |
Amount that his aunt spent on 5 cups
= 5 x 6.70
= $33.50
Let the cost of 1 bowl be 1 B.
If Asher's aunt spent $16.40 less, each would pay the same amount.
10 B + 16.40 = 7 B + 33.50 - 16.40
10 B - 7 B = 33.50 - 16.40
3 B = 17.10
1 B = 17.10 ÷ 3 = 5.70
Total amount that Asher and his aunt spent
= 10 B + 7 B + 33.50
= 17 B + 33.50
= 17 x 5.70 + 33.50
= 96.90 + 33.50
= $130.40
Answer(s): $130.40
