Jane and Hilda had the same number of pens. After Jane had given away 66 pens, Hilda had 4 times as many pens as Jane. How many pens did each of them have at first?
| |
Jane |
Hilda |
| Before |
1 u + 66 |
4 u |
| Change |
- 66 |
|
| After |
1 u |
4 u |
Number of pens that Hilda had remains unchanged.
Number of pens that Jane and Hilda had at first is equal.
4 u = 1 u + 66
4 u - 1 u = 66
3 u = 66
1 u = 66 ÷ 3= 22
Number of pens that each of them had at first
= 1 u + 66
= 22 + 66
= 88
Answer(s): 88
