Owen and Brandon had 30 muffins altogether. After Owen ate
14 of his muffins and Brandon ate 4 muffins, the number of muffins Brandon had left was thrice the number of muffins Owen had left. How many more muffins did Brandon have than Owen at first?

Owen |
Brandon |
Total |
Before |
4 u |
9 u + 4 |
30 |
Change |
- 1 u |
- 4 |
|
After |
3 u |
|
|
Comparing Owen and Brandon in the end |
1x3 = 3 u |
3x3 = 9 u |
|
The number of muffins that Owen had in the end is the same. Make the number of muffins that Owen had in the end the same. LCM of 3 and 1 is 3.
Total number of muffins at first
= 4 u + 9 u + 4
= 13 u + 4
13 u + 4 = 30
13 u = 30 - 4
13 u = 26
1 u = 26 ÷ 13 = 2
Number of muffins that Owen had at first
= 4 u
= 4 x 2
= 8
Number of muffins that Brandon had at first
= 30 - 8
= 22
Number of muffins that Brandon had more than Owen at first
= 22 - 8
= 14
Answer(s): 14
