Lucy had 19 more lollipops than Archie at first. After Archie had eaten 13 of his lollipops, Lucy had 5 times as many lollipops as Archie. How many lollipops did Lucy and Archie have in total at first?

Archie |
Total |
| Before |
1 u + 13 + 19 |
1 u + 13 |
6 u + 13 |
| Change |
|
- 13 |
|
| After |
5 u |
1 u |

The number of lollipops that Lucy had at first remains unchanged.
5 u = 1 u + 13 + 19
5 u - 1 u = 32
4 u = 32
1 u = 32 ÷ 4 = 8
Number of lollipops that they had at first
= 6 u + 13
= 6 x 8 + 13
= 48 + 13
= 61
Answer(s): 61
