Amount that his cousin spent on 5 cups
= 5 x 1.30
= $6.50
Let the cost of 1 bowl be 1 B.
If Howard spent $13.90 less, each would pay the same amount.
8 B - 13.90 = 5 B + 6.50
8 B - 5 B = 6.50 + 13.90
8 B - 5 B = 20.40
3 B = 20.40
1 B = 20.40 ÷ 3 = 6.80
Total amount that Howard and his cousin spent
= 8 B + 5 B + 6.50
= 13 B + 6.50
= 13 x 6.80 + 6.50
= 88.40 + 6.50
= $94.90
Answer(s): $94.90
