Yesterday, Riordan had 73 wafers and 90 shortbreads. This morning, he sold 25 wafers and bought some more shortbreads. Now he has five times as many shortbreads as wafers. How many shortbreads did he buy today?
| |
Wafers |
Shortbreads |
| Before |
73 |
90 |
| Change |
- 25 |
+ ? |
| After |
1 u |
5 u |
Number of wafers in the end
= 73 - 25
= 48
1 u = 48
Number of shortbreads in the end
= 5 u
= 5 x 48
= 240
Number of shortbreads that Riordan bought today
= 5 u - 90
= 240 - 90
= 150
Answer(s): 150
