Ahmad had $70.70 less than Opal. He spent
67 of his money on a file which cost $9.60. Opal spent
29 of her money on a jumpsuit. How much had Opal left?
|
Ahmad |
Opal |
Before |
7 u |
9 p |
Change |
- 6 u |
- 2 p |
After |
1 u |
7 p |
Amount that Ahmad spent on the file = 6 u
6 u = 9.60
1 u = 9.60 ÷ 6 = 1.60
Amount that Ahmad had at first
= 7 u
= 7 x 1.60
= $11.20
Amount that Opal had at first
= 11.20 + 70.70
= $81.90
Fraction of money that Opal had left
= 1 -
29 =
79 Amount that Opal had at first = 9 p
9 p = 81.90
1 p = 81.90 ÷ 9 = 9.10
Amount that Opal had left
= 7 p
= 7 x 9.10
= $63.70
Answer(s): $63.70
