The number of vanilla muffins Eric baked was
38 of the total number of muffins. After baking another 14 vanilla muffins, the number of vanilla muffins became
23 of the total number of muffins. How many muffins did she bake at first?
|
Vanilla muffins |
Other muffins |
Total muffins |
Before |
3 u |
5 u |
8 u |
Change |
+ 14 |
|
|
After |
2x5 = 10 u |
1x5 = 5 u |
3x5 = 15 u |
The number of other muffins remains unchanged. Make the number of other muffins the same. LCM of 5 and 1 is 5.
Number of more vanilla muffins baked
= 10 u - 3 u
= 7 u
7 u = 14
1 u = 14 ÷ 7 = 2
Number of muffins that Eric baked at first
= 8 u
= 8 x 2
= 16
Answer(s): 16
