+36 Blake and Andy have a collection of computer games. Blake found 3 out of every 4 computer games in the collection. Andy found 18 fewer computer games than Blake. How many computer games are in their collection?
+526 Lets assume there are \(x\) games in their collection.
So, now we have
Blake found = \({3x \over 4}\) video games
Andy found = \({3x \over 4}-18\) video games
Back to the question... total no. of video games are \(x\)
∴ \({3x \over 4}+{3x \over 4} -18=x\)
\({6x \over 4}-x=18\)
\(2x=72\)
\(x=36\)
Hence, there are 36 video games in their collection.
