Jane had 37 more smoothed stones than Gabby at first. After Jane bought another 14 smoothed stones, she had four times as many smoothed stones as Gabby. How many smoothed stones did Jane have at first?
| |
Jane |
Gabby |
| Before |
1 u + 37 |
1 u |
| Change |
+ 14 |
|
| After |
1 u + 51 |
1 u |
Number of smoothed stones Jane had in the end
= 4 x 1 u
= 4 u
4 u = 1 u + 51
4 u - 1 u = 51
3 u = 51
1 u = 51 ÷ 3 = 17
Number of smoothed stones Jane had at first
= 1 u + 37
= 17 + 37
= 54
Answer(s): 54
