STUGO 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 of drink was sold so that they can make predictions for
future sales. Mrs. Mendoza 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?

Number of hot chocolate = 250

Number of coffee = 25

Step-by-step explanation:

Given:

Total income = $200 = 20,000 cents

Number of total item sell = 275

Amount of each hot chocolate = 75 cents

Amount of each coffee = 50 cents

Find:

Number of each drink sold

Computation:

Assume

Number of hot chocolate = x

Number of coffee = 275 - x

So,

Total income = [Number of hot chocolate][Amount of each hot chocolate] + [Number of coffee][Amount of each coffee]

20,000 = [x][75] + [275-x][50]

20,000 = 75x + 13,750 - 50x

x = 250

Number of hot chocolate = 250

Number of coffee = 275 - 250

Number of coffee = 25

21/58.
