Kimberly has 4 times as many tarts as Shiyun. The total number of Kimberly's and Shiyun's tarts is 7 times of Elyse's. Kimberly and Shiyun have 300 tarts more than Elyse's. How many more tarts does Kimberly have than Shiyun?
| Kimberly |
Shiyun |
Elyse |
| 4x7 |
1x7 |
|
| 7x5 |
1x5 |
| 28 u |
7 u |
5 u |
The total number of tarts that Kimberly and Shiyun have is repeated. Make the total number of tarts that Kimberly and Shiyun have the same. LCM of 5 and 7 is 35.
Total number of tarts that Kimberly and Shiyun have
= 28 u + 7 u
= 35 u
Number of more tarts that Kimberly and Shiyun have than Elyse
= 35 u - 5 u
= 30 u
30 u = 300
1 u = 300 ÷ 30 = 10
Number of more tarts that Kimberly has than Shiyun
= 28 u - 7 u
= 21 u
= 21 x 10
= 210
Answer(s): 210
