Jeremy bought some pastries. He bought some croissants with $8.60 more than half his money. He then bought some cupcakes with $4.40 less than half of his remaining money. He then had $12.20 left. How much did he pay for the croissants?
| Croissants |
Remaining amount |
| 1 u + $8.60 |
1 u - $8.60 |
| |
Cupcakes |
Left |
| |
1 p - $4.40 |
1 p + $4.40 |
| |
|
$12.20 |
Working backwards.
Amount that Jeremy had left = 1 p + 4.40
1 p + 4.40 = 12.20
1 p = 12.20 - 4.40 = 7.80
Remaining amount after he bought some croissants
= 2 p
= 2 x 7.80
= $15.60
Remaining amount after he bought some croissants = 1 u - 8.60
1 u - 8.60 = 15.60
1 u = 15.60 + 8.60
1 u = 24.20
Amount that Jeremy spent on some croissants
= 1 u + 8.60
= 24.20 + 8.60
= $32.80
Answer(s): $32.80
