Ivory has 3 times as many scones as Sabrina. The total number of Ivory's and Sabrina's scones is 5 times of Cindy's. Ivory and Sabrina have 64 scones more than Cindy's. How many more scones does Ivory have than Sabrina?
| Ivory |
Sabrina |
Cindy |
| 3x5 |
1x5 |
|
| 5x4 |
1x4 |
| 15 u |
5 u |
4 u |
The total number of scones that Ivory and Sabrina have is repeated. Make the total number of scones that Ivory and Sabrina have the same. LCM of 4 and 5 is 20.
Total number of scones that Ivory and Sabrina have
= 15 u + 5 u
= 20 u
Number of more scones that Ivory and Sabrina have than Cindy
= 20 u - 4 u
= 16 u
16 u = 64
1 u = 64 ÷ 16 = 4
Number of more scones that Ivory has than Sabrina
= 15 u - 5 u
= 10 u
= 10 x 4
= 40
Answer(s): 40
