Jeremy bought some pastries. He bought some biscuits with $6.50 more than half his money. He then bought some cupcakes with $1.20 less than half of his remaining money. He then had $9.40 left. How much did he pay for the biscuits?
| Biscuits |
Remaining amount |
| 1 u + $6.50 |
1 u - $6.50 |
| |
Cupcakes |
Left |
| |
1 p - $1.20 |
1 p + $1.20 |
| |
|
$9.40 |
Working backwards.
Amount that Jeremy had left = 1 p + 1.20
1 p + 1.20 = 9.40
1 p = 9.40 - 1.20 = 8.20
Remaining amount after he bought some biscuits
= 2 p
= 2 x 8.20
= $16.40
Remaining amount after he bought some biscuits = 1 u - 6.50
1 u - 6.50 = 16.40
1 u = 16.40 + 6.50
1 u = 22.90
Amount that Jeremy spent on some biscuits
= 1 u + 6.50
= 22.90 + 6.50
= $29.40
Answer(s): $29.40
