Explanation:
The question is Incomplete. Find the complete question in the attachment.
Number of muffins made by Franco =12
Number of Badly Burnt Muffins =2
Number of non burned muffins =12-2=10
Franco served
![(7)/(10) $ of the non burned muffins = $ (7)/(10)*10=7$ muffins](https://img.qammunity.org/2021/formulas/mathematics/college/xfqux6ljnj63zutjx3y4esufe7kgbaoqby.png)
Therefore, the number of non burned muffins that remains =10-7 =3
We can then say the fraction of the non-burned muffins that remains
![=(3)/(10)](https://img.qammunity.org/2021/formulas/mathematics/college/yq16bb2fhyy6scy8ho4lbpx8061gbgguxp.png)
Therefore, the correct equation is in Option B:
![(10)/(10)-(7)/(10)=(3)/(10)](https://img.qammunity.org/2021/formulas/mathematics/high-school/ljmuwvmf3l8zcy1hwj84qin6wwzu2o4d3u.png)
