Answer:
Option B.
Step-by-step explanation:
This question is incomplete; find the complete question with the attachment.
Franco made number of muffins = a dozen
A dozen muffins = 12 muffins
Number of muffins were burned = 2
Remaining muffins = 12 - 2 = 10
Franco served 7 of the remaining non-burned muffins,
Fraction of muffins served = [tex]\frac{7}{10}[/tex]
Remaining muffins = 3
Fraction of remaining muffins = [tex]\frac{3}{10}[/tex]
Fraction of remaining non-burned muffins we can get from,
[tex]\frac{10}{10}-\frac{7}{10}=\frac{3}{10}[/tex]
Option B is the correct equation.
