Pamela has 5 times as many croissants as Lynn. The total number of Pamela's and Lynn's croissants is 4 times of Betty's. Pamela and Lynn have 63 croissants more than Betty's. How many more croissants does Pamela have than Lynn?
| Pamela |
Lynn |
Betty |
| 5x2 |
1x2 |
|
| 4x3 |
1x3 |
| 10 u |
2 u |
3 u |
The total number of croissants that Pamela and Lynn have is repeated. Make the total number of croissants that Pamela and Lynn have the same. LCM of 6 and 4 is 12.
Total number of croissants that Pamela and Lynn have
= 10 u + 2 u
= 12 u
Number of more croissants that Pamela and Lynn have than Betty
= 12 u - 3 u
= 9 u
9 u = 63
1 u = 63 ÷ 9 = 7
Number of more croissants that Pamela has than Lynn
= 10 u - 2 u
= 8 u
= 8 x 7
= 56
Answer(s): 56
