Tiffany and Victoria had the same number of stamps. After Tiffany had given away 72 stamps, Victoria had 4 times as many stamps as Tiffany. How many stamps did each of them have at first?
| |
Tiffany |
Victoria |
| Before |
1 u + 72 |
4 u |
| Change |
- 72 |
|
| After |
1 u |
4 u |
Number of stamps that Victoria had remains unchanged.
Number of stamps that Tiffany and Victoria had at first is equal.
4 u = 1 u + 72
4 u - 1 u = 72
3 u = 72
1 u = 72 ÷ 3= 24
Number of stamps that each of them had at first
= 1 u + 72
= 24 + 72
= 96
Answer(s): 96
