14 of her stamps and Marion used
19 of her stamps. They used 104 stamps altogether. How many stamps did Marion have in the end?

| Before |
4x9 =
36 u |
9x4 =
36 u |
| Change |
- 1x9 =
- 9 u |
- 1x4 =
- 4 u |
| After |
3x9 =
27 u |
8x4 =
32 u |
The number of stamps that Shannon and Marion each had at first is the same. Make the number of stamps that Shannon and Marion each had at first the same. LCM of 4 and 9 is 36.
Number of stamps that Shannon and Marion used
= 9 u + 4 u
= 13 u
13 u = 104
1 u = 104 ÷ 13 = 8
Number of stamps that Marion had in the end
= 32 u
= 32 x 8
= 256
Answer(s): 256
