Tiffany and Jen had an equal number of sweets. After Tiffany bought another 28 sweets and Jen bought another 4 sweets, Tiffany had thrice as many sweets as Jen. Find the number of sweets that each of them had at first.

Tiffany |
Jen |
| Before |
3 u - 28 |
1 u - 4 |
| Change |
+ 28 |
+ 4 |
| After |
3 u |
1 u |
The number of sweets that Tiffany and Jen had at first is the same.
3 u - 28 = 1 u - 4
3 u - 1 u = 28 - 4
2 u = 24
1 u = 24 ÷ 2 = 12
Number of sweets that each had at first
= 12 - 4
= 8
Answer(s): 8
