38 of the total number of croissants. After baking another 108 cranberry croissants, the number of cranberry croissants became
34 of the total number of croissants. How many croissants did she bake at first?

| After |
3x5 =
15 u |
1x5 =
5 u |
4x5 =
20 u |
The number of other croissants remains unchanged. Make the number of other croissants the same. LCM of 5 and 1 is 5.
Number of more cranberry croissants baked
= 15 u - 3 u
= 12 u
12 u = 108
1 u = 108 ÷ 12 = 9
Number of croissants that Cody baked at first
= 8 u
= 8 x 9
= 72
Answer(s): 72
