Dragon Fruits |
Limes |
| Before |
3 u |
10 u - 84 |
| Change |
- 1 u |
+ 84 |
| After |
2 u |
10 u |
The number of limes and dragon fruits at first is the same.
10 u - 84 = 3 u
10 u - 3 u = 84
7 u = 84
1 u = 84 ÷ 7 = 12
Number of dragon fruits that she had at first
= 3 u
= 3 x 12
= 36
Answer(s): 36
