Let's say "V" represents the amount of vanilla milkshakes left in the machine and "C" represents the amount of chocolate milkshakes left in the machine.
The vanilla milkshake machine has a capacity of 300 cups, so the equation for vanilla milkshakes left is:
V = 300 - 15x (since it sells 15 cups per day)
The chocolate milkshake machine has a capacity of 280 cups, so the equation for chocolate milkshakes left is:
C = 280 - 20x (since it sells 20 cups per day)
To find when the two machines will have the same amount of milkshake left, we need to find the value of x that makes V equal to C:
300 - 15x = 280 - 20x
Now, we can solve for x
A diner makes vanilla milkshakes and chocolate milkshakes. The vanilla milkshake machine has a 300-cup capacity, and sells 15 cups per day. The chocolate milkshake machine has a 280-cup capacity, and sells 20 cups per day. Write an equation to show when the two machines will have the same amount of milkshake left. Use x as your variable.
