Answer:
250 cups of chocolate and 25 cups of coffee.
Step-by-step explanation:
Let's call
x: the number of chocolate cups
y: the number of coffee cups.
If they made $200, we can write the following equation:
0.75x + 0.50y = 200
Because they sell hot chocolate for $0.75 and coffee for $0.50.
Additionally, they sell 275 cups, so:
x + y = 275
Solving the equation for y, we get:
x + y - x = 275 - x
y = 275 - x
Now, we can substitute y = 275 - x on the first equation:
0.75x + 0.50y = 200
0.75x + 0.50(275 - x) = 200
Then, we can solve the equation for x:
0.75x + 0.50(275) - 0.50x = 200
0.75x + 137.5 - 0.50x = 200
0.25x + 137.5 = 200
0.25x + 137.5 - 137.5 = 200 - 137.5
0.25x = 62.5
0.25x/0.25 = 62.5/0.25
x = 250
Finally, replacing x by 250, we can find the value of y as follows:
y = 275 - x
y = 275 - 250
y = 25
So, they sold 250 cups of chocolate and 25 cups of coffee.
