34 of his money on a file which cost $7.20. Wendy spent
29 of her money on a sweater. How much had Wendy left?
| |
Cody |
Wendy |
| Before |
4 u |
9 p |
| Change |
- 3 u |
- 2 p |
| After |
1 u |
7 p |
Amount that Cody spent on the file = 3 u
3 u = 7.20
1 u = 7.20 ÷ 3 = 2.40
Amount that Cody had at first
= 4 u
= 4 x 2.40
= $9.60
Amount that Wendy had at first
= 9.60 + 36.30
= $45.90
Fraction of money that Wendy had left
= 1 -
29 =
79 Amount that Wendy had at first = 9 p
9 p = 45.90
1 p = 45.90 ÷ 9 = 5.10
Amount that Wendy had left
= 7 p
= 7 x 5.10
= $35.70
Answer(s): $35.70
