Question 664182: The northeast riders 4h club sold orange juice and cocoa at their horse show. The orange juice cost 20 cents per glass and the cocoa cost 15 cent per cup. They sold 20 more cups of cocoa than glasses of orange juice. How much of each drink did they sell if the total receipts were $11.40?
I can't figure out the proper equations.
Thanks

For my sanity, o.j. is o, and cocoa is c.
.2o+ .15c= 11.4
o+20= c
The above two lines are the equations you would use.
