Jade has 4 times as many puffs as Ivory. The total number of Jade's and Ivory's puffs is 4 times of Sabrina's. Jade and Ivory have 30 puffs more than Sabrina's. How many more puffs does Jade have than Ivory?
| Jade |
Ivory |
Sabrina |
| 4x4 |
1x4 |
|
| 4x5 |
1x5 |
| 16 u |
4 u |
5 u |
The total number of puffs that Jade and Ivory have is repeated. Make the total number of puffs that Jade and Ivory have the same. LCM of 5 and 4 is 20.
Total number of puffs that Jade and Ivory have
= 16 u + 4 u
= 20 u
Number of more puffs that Jade and Ivory have than Sabrina
= 20 u - 5 u
= 15 u
15 u = 30
1 u = 30 ÷ 15 = 2
Number of more puffs that Jade has than Ivory
= 16 u - 4 u
= 12 u
= 12 x 2
= 24
Answer(s): 24
