The ratio of Kaylee's stickers to Avery's stickers at first was 3 : 5. After Kaylee gave Avery 60 stickers, the ratio of Kaylee's stickers to Avery's stickers is 1 : 3. What was the number of stickers they had in total?
| |
Kaylee |
Avery |
Total |
| Before |
3x4 =
12 u |
5x4 =
20 u
|
8x4 =
32 u |
| Change |
- 60 |
+ 60 |
|
| After |
1x8 =
8 u |
3x8 =
24 u |
4x8 =
32 u |
Number of stickers that Kaylee gave Avery
= 12 u - 8 u
= 4 u
4 u = 60
1 u = 60 ÷ 4 = 15
Total number of stickers that they had
= 32 u
= 32 x 15
= 480
Answer(s): 480
