Tom and Fabian had 38 muffins altogether. After Tom ate
13 of his muffins and Fabian ate 2 muffins, the number of muffins Fabian had left was thrice the number of muffins Tom had left. How many more muffins did Fabian have than Tom at first?

Tom |
Fabian |
Total |
Before |
3 u |
6 u + 2 |
38 |
Change |
- 1 u |
- 2 |
|
After |
2 u |
|
|
Comparing Tom and Fabian in the end |
1x2 = 2 u |
3x2 = 6 u |
|
The number of muffins that Tom had in the end is the same. Make the number of muffins that Tom had in the end the same. LCM of 2 and 1 is 2.
Total number of muffins at first
= 3 u + 6 u + 2
= 9 u + 2
9 u + 2 = 38
9 u = 38 - 2
9 u = 36
1 u = 36 ÷ 9 = 4
Number of muffins that Tom had at first
= 3 u
= 3 x 4
= 12
Number of muffins that Fabian had at first
= 38 - 12
= 26
Number of muffins that Fabian had more than Tom at first
= 26 - 12
= 14
Answer(s): 14
