Henry bought some pastries. He bought some scones with $6.90 more than half his money. He then bought some biscuits with $5.60 less than half of his remaining money. He then had $9.90 left. How much did he pay for the scones?
| Scones |
Remaining amount |
| 1 u + $6.90 |
1 u - $6.90 |
| |
Biscuits |
Left |
| |
1 p - $5.60 |
1 p + $5.60 |

|
$9.90 |
Working backwards.
Amount that Henry had left = 1 p + 5.60
1 p + 5.60 = 9.90
1 p = 9.90 - 5.60 = 4.30
Remaining amount after he bought some scones
= 2 p
= 2 x 4.30
= $8.60
Remaining amount after he bought some scones = 1 u - 6.90
1 u - 6.90 = 8.60
1 u = 8.60 + 6.90
1 u = 15.50
Amount that Henry spent on some scones
= 1 u + 6.90
= 15.50 + 6.90
= $22.40
Answer(s): $22.40
