Cody and Cole had 33 muffins altogether. After Cody ate
14 of his muffins and Cole ate 3 muffins, the number of muffins Cole had left was twice the number of muffins Cody had left. How many more muffins did Cole have than Cody at first?

Cody |
Cole |
Total |
Before |
4 u |
6 u + 3 |
33 |
Change |
- 1 u |
- 3 |
|
After |
3 u |
|
|
Comparing Cody and Cole in the end |
1x3 = 3 u |
2x3 = 6 u |
|
The number of muffins that Cody had in the end is the same. Make the number of muffins that Cody had in the end the same. LCM of 3 and 1 is 3.
Total number of muffins at first
= 4 u + 6 u + 3
= 10 u + 3
10 u + 3 = 33
10 u = 33 - 3
10 u = 30
1 u = 30 ÷ 10 = 3
Number of muffins that Cody had at first
= 4 u
= 4 x 3
= 12
Number of muffins that Cole had at first
= 33 - 12
= 21
Number of muffins that Cole had more than Cody at first
= 21 - 12
= 9
Answer(s): 9
