Yesterday, Michael had 60 wafers and 44 croissants. This morning, he sold 30 wafers and bought some more croissants. Now he has thrice as many croissants as wafers. How many croissants did he buy today?
| |
Wafers |
Croissants |
| Before |
60 |
44 |
| Change |
- 30 |
+ ? |
| After |
1 u |
3 u |
Number of wafers in the end
= 60 - 30
= 30
1 u = 30
Number of croissants in the end
= 3 u
= 3 x 30
= 90
Number of croissants that Michael bought today
= 3 u - 44
= 90 - 44
= 46
Answer(s): 46
