Amount that his aunt spent on 2 glasses
= 2 x 4.30
= $8.60
Let the cost of 1 bowl be 1 B.
If Ken spent $5.60 less, each would pay the same amount.
10 B - 5.60 = 8 B + 8.60
10 B - 8 B = 8.60 + 5.60
10 B - 8 B = 14.20
2 B = 14.20
1 B = 14.20 ÷ 2 = 7.10
Total amount that Ken and his aunt spent
= 10 B + 8 B + 8.60
= 18 B + 8.60
= 18 x 7.10 + 8.60
= 127.80 + 8.60
= $136.40
Answer(s): $136.40
