Jenson and Mark had an equal number of lollipops at first. Jenson and Mark ate 21 and 3 lollipops respectively. In the end, Mark has four times as many lollipops as Jenson. How many lollipops did each of them has at first?
| |
Jenson |
Mark |
| Before |
1 u + 21 |
4 u + 3 |
| Change |
- 21 |
- 3 |
| After |
1 u |
4 u |
Jenson and Mark had an equal number of lollipops at first.
4 u + 3 = 1 u + 21
4 u - 1 u = 21 - 3
3 u = 18
1 u = 18 ÷ 3 = 6
Number of lollipops that each of them had at first
= 1 u + 21
= 6 + 21
= 27
Answer(s): 27
