The concession at VHS sells hot chocolate and coffee at the high school football games. At the last game, they had sales of $200.

They need to keep track of how many of each type drink was sold

so that they can make predictions for future sales. Monica knows

that they used 275 cups that night. If the hot chocolate sells for 75

cents and coffee sells for 50 cents, how much of each type of drink

were sold?
