45 of her money on some shortbreads and
25 of her remaining money on 7 puffs. Each puff cost twice as much as a shortbread. How many shortbreads did she buy?

2x1 |
3x1 |
| 20 u |
2 u |
3 u |
Cost of 1 puff = Cost of 2 shortbreads
(x7)Cost of 7 puffs = Cost of 14 shortbreads
2 u = 14
1 u = 14 ÷ 2 = 7
Number of shortbreads that Kimberly bought
= 20 u
= 20 x 7
= 140
