Yesterday, Zeph had 78 croissants and 80 shortbreads. This morning, he sold 30 croissants and bought some more shortbreads. Now he has five times as many shortbreads as croissants. How many shortbreads did he buy today?
| |
Croissants |
Shortbreads |
| Before |
78 |
80 |
| Change |
- 30 |
+ ? |
| After |
1 u |
5 u |
Number of croissants in the end
= 78 - 30
= 48
1 u = 48
Number of shortbreads in the end
= 5 u
= 5 x 48
= 240
Number of shortbreads that Zeph bought today
= 5 u - 80
= 240 - 80
= 160
Answer(s): 160
