Percy solved the equation by expanding the expression on the left-hand side, and this is incorrect
<h3>How to determine the true solution?</h3>
The equation is given as:
x^2 + 7x + 12 = 12
The first step in solving the equation is to equate the equation to 0.
i.e.
x^2 + 7x + 12 - 12 = 0
This given
x^2 + 7x = 0
From the question, Percy solved the equation by expanding the expression on the left-hand side
Hence, Percy's solution is incorrect

Answer:
She can make up to 4 smoothies.
Step-by-step explanation:
In order to calculate the number of smoothies Carol can make we need to first convert the total amount of yogurt she has from a mixed number to a pure fraction, this is shown bellow:
total amount of yogurt = 1 5/8 = 1 + 5/8
total amount of yogurt = 8/8 + 5/8 = 13/8
Now we can use this number and divide it by the amount of yogurt each smoothie takes. So we have:
number of smoothies = (13/8)/(1/3)
number of smoothies = (13/8)*(3/1) = 39/8 = 4.875 smoothies
Since she won't make a fraction of a smoothie she can make up to 4 smoothies.
