Answer:

The bookstore has 48 left.

Explanation:

If yesterday the bookstore solve 1/4 of 80 magazines then it sold:

[tex]\frac{1}{4}[/tex] X 80 →  [tex]\frac{80}{4}[/tex} →  20

So at the end of the day it had  

80-20

magazines left or 60 total magazines left.

Today it sold 185 of 60 (the total left from yesterday) or:

[tex]\frac{1}{5}[/tex] X 60  →  [tex]\frac{60}{5}[/tex] → 12

So, at the end of today it had  

60-12

magazines left or 48 total magazines left.
