Andy bought some pastries. He bought some scones with $8.50 more than half his money. He then bought some wafers with $1.90 less than half of his remaining money. He then had $6.50 left. How much did he pay for the scones?
| Scones |
Remaining amount |
| 1 u + $8.50 |
1 u - $8.50 |
| |
Wafers |
Left |
| |
1 p - $1.90 |
1 p + $1.90 |
| |
|
$6.50 |
Working backwards.
Amount that Andy had left = 1 p + 1.90
1 p + 1.90 = 6.50
1 p = 6.50 - 1.90 = 4.60
Remaining amount after he bought some scones
= 2 p
= 2 x 4.60
= $9.20
Remaining amount after he bought some scones = 1 u - 8.50
1 u - 8.50 = 9.20
1 u = 9.20 + 8.50
1 u = 17.70
Amount that Andy spent on some scones
= 1 u + 8.50
= 17.70 + 8.50
= $26.20
Answer(s): $26.20
