$2.70 more |
Amount that his cousin spent on 5 cups
= 5 x 5.50
= $27.50
Let the cost of 1 bowl be 1 B.
If Jenson's cousin spent $2.70 less, each would pay the same amount.
8 B + 2.70 = 4 B + 27.50 - 2.70
8 B - 4 B = 27.50 - 2.70
4 B = 24.80
1 B = 24.80 ÷ 4 = 6.20
Total amount that Jenson and his cousin spent
= 8 B + 4 B + 27.50
= 12 B + 27.50
= 12 x 6.20 + 27.50
= 74.40 + 27.50
= $101.90
Answer(s): $101.90
