Tina and Shannon had an equal number of sweets. After Tina bought another 27 sweets and Shannon bought another 5 sweets, Tina had thrice as many sweets as Shannon. Find the number of sweets that each of them had at first.
| |
Tina |
Shannon |
| Before |
3 u - 27 |
1 u - 5 |
| Change |
+ 27 |
+ 5 |
| After |
3 u |
1 u |
The number of sweets that Tina and Shannon had at first is the same.
3 u - 27 = 1 u - 5
3 u - 1 u = 27 - 5
2 u = 22
1 u = 22 ÷ 2 = 11
Number of sweets that each had at first
= 11 - 5
= 6
Answer(s): 6
