bananas. Calvin spends twice as much paying for 
muffins and 
bananas. A muffin is how many times as expensive as a banana?
Solution
Let 
be the cost of a muffin and 
be the cost of a banana. From the given information, ![\[2m+16b=2(4m+3b)=8m+6b\Rightarrow 10b=6m\Rightarrow m=\frac{10}{6}b=\text{(B) } \boxed{\frac{5}{3}b}\]](http://latex.artofproblemsolving.com/2/9/d/29d6b94d062cae85119a105b3187dc866ed30ded.png)
