Yesterday, Luke had 70 cupcakes and 12 shortbreads. This morning, he sold 36 cupcakes and bought some more shortbreads. Now he has twice as many shortbreads as cupcakes. How many shortbreads did he buy today?
| |
Cupcakes |
Shortbreads |
| Before |
70 |
12 |
| Change |
- 36 |
+ ? |
| After |
1 u |
2 u |
Number of cupcakes in the end
= 70 - 36
= 34
1 u = 34
Number of shortbreads in the end
= 2 u
= 2 x 34
= 68
Number of shortbreads that Luke bought today
= 2 u - 12
= 68 - 12
= 56
