Zeph and Owen had 97 macarons altogether. After Zeph ate
14 of his macarons and Owen ate 7 macarons, the number of macarons Owen had left was twice the number of macarons Zeph had left. How many more macarons did Owen have than Zeph at first?

Before |
4 u |
6 u + 7 |
97 |
Change |
- 1 u |
- 7 |
|
After |
3 u |
|
|
Comparing Zeph and Owen in the end |
1x3 = 3 u |
2x3 = 6 u |
|
The number of macarons that Zeph had in the end is the same. Make the number of macarons that Zeph had in the end the same. LCM of 3 and 1 is 3.
Total number of macarons at first
= 4 u + 6 u + 7
= 10 u + 7
10 u + 7 = 97
10 u = 97 - 7
10 u = 90
1 u = 90 ÷ 10 = 9
Number of macarons that Zeph had at first
= 4 u
= 4 x 9
= 36
Number of macarons that Owen had at first
= 97 - 36
= 61
Number of macarons that Owen had more than Zeph at first
= 61 - 36
= 25
Answer(s): 25
