Amount that his friend spent on 4 wine glasses
= 4 x 5.90
= $23.60
Let the cost of 1 bowl be 1 B.
If Jenson spent $2.50 less, each would pay the same amount.
8 B - 2.50 = 5 B + 23.60
8 B - 5 B = 23.60 + 2.50
8 B - 5 B = 26.10
3 B = 26.10
1 B = 26.10 ÷ 3 = 8.70
Total amount that Jenson and his friend spent
= 8 B + 5 B + 23.60
= 13 B + 23.60
= 13 x 8.70 + 23.60
= 113.10 + 23.60
= $136.70
Answer(s): $136.70
