Problem
A jar contains 
different colors of gumdrops. 
are blue, 
are brown, 
are red, 
are yellow, and other 
gumdrops are green. If half of the blue gumdrops are replaced with brown gumdrops, how many gumdrops will be brown?
Solution
We do 
to find the percent of gumdrops that are green. We find that 
of the gumdrops are green. That means there are 
gumdrops. If we replace all blue gumdrops with green gumdrops, then 
of the jar's gumdrops are brown.
