Question

A dozen bran muffins cost $9.48. Which equation represents the cost, y, of x muffins

Answer 1

12y+9.48x=0

Explanation:

Note dozen means 12 in mathematics

So 12 muffins cost $9.48

X muffins cost $y

So let's cross multiply

12×y=9.48×x

12y=9.48x

Substrate 9.48x from both sides

12y-9.48x=0

So the final equation is 12y-9.48x=0
