5 bowls + 5 wine glasses = 5 bowls + 38.50 |

$13.30 more |
Amount that his sister spent on 5 wine glasses
= 5 x 7.70
= $38.50
Let the cost of 1 bowl be 1 B.
If Zane's sister spent $13.30 less, each would pay the same amount.
8 B + 13.30 = 5 B + 38.50 - 13.30
8 B - 5 B = 38.50 - 13.30
3 B = 25.20
1 B = 25.20 ÷ 3 = 8.40
Total amount that Zane and his sister spent
= 8 B + 5 B + 38.50
= 13 B + 38.50
= 13 x 8.40 + 38.50
= 109.20 + 38.50
= $147.70
Answer(s): $147.70
