Kimberly had 11 more scones than Dana at first. After Kimberly ate 3 scones, she had five times as many scones as Dana in the end. How many scones did Dana have?
| |
Dana |
Kimberly |
| Before |
1 u |
1 u + 11 |
| Change |
|
- 3 |
| After |
1 u |
1 u + 8 |
Comparing Dana
and Kimberly in the end |
1 u |
5 u |
The number of scones that Dana had remains unchanged.
Number of scones that Kimberly had in the end
= 5 x 1 u
= 5 u
5 u = 1 u + 8
5 u - 1 u = 8
4 u = 8
1 u = 8 ÷ 4 = 2
Number of scones that Dana had
= 1 u
= 2
Answer(s): 2
