Answer:
They sold 120 milkshakes that day
Step-by-step explanation:
We can set up a proportion


Note: If you have some value,
, and it is
of the total amount, you can find the value by doing the equation 
You need to subtract everything to the left side and set it equal to zero. Combine like terms.
Then, the coefficient of x^2 is a, the coefficient of x is b, and the constant term is c.
4x^2 - 5 = 3x + 4
4x^2 - 3x - 5 - 4 = 0
4x^2 - 3x - 9 = 0
a = 4; b = -3; c = -9


D) because the final answer should be 8/3. See the attachment.
