Answer:

Coffee = 25

Hot Chocolate = 250

Step-by-step explanation:

Coffee: c

Hot Chocolate: h

0.75h + 0.50c = 200

h + c = 275

h + c = 275

h = 275 - c

0.75h + 0.50c = 200

0.75(275 - c) + 0.5c = 200

206.25 - 0.75c + 0.5c = 200

-0.25c = -6.25

-0.25c/-0.25 = -6.25/-0.25

c = 25

0.75h + 0.5(25) = 200

0.75h + 12.5 = 200

0.75h = 200 - 12.5

0.75h = 187.5

0.75h/0.75 = 187.5

h = 250

Check: c = 25; h = 250

0.75h + 0.50c = 200

h + c = 275

0.75(250) + 0.5(25) = 200

187.5 + 12.5 = 200

200 = 200

h + c = 275

250 + 25 = 275

275 = 275

The drama club sold 250 hot chocolates and 25 coffee drinks.

Equation

Equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the number of hot chocolate and y represent the number of coffee. From the question the equation are:

  • x + y = 275   (1)
  • 0.75x + 0.5y = 200 (2)

From both equations:

x = 250, y = 25
