John and Tammy had the same number of lollipops. After Tammy gave away 21 lollipops and John gave away 41 lollipops, Tammy had 3 times as many lollipops as John. How many lollipops did each of them have at first?
| |
John |
Tammy |
| Before |
1 u + 41 |
3 u + 21 |
| Change |
- 41 |
- 21 |
| After |
1 u |
3 u |
The number of lollipops that John and Tammy had at first is the same.
3 u + 21 = 1 u + 41
3 u - 1 u = 41 - 21
2 u = 20
1 u = 20 ÷ 2 = 10
Number of lollipops that each of them had at first
= 1 u + 41
= 10 + 41
= 51
Answer(s): 51
