Step-by-step explanation:
Let the amount of wheat is x and amount of corn is y.
The total amount of pasta is
- x + y = 57
Amount of protein in same pasta is
- 5% of x + 10% of y = 4
or
- 0.05x + 0.1y = 4
The graphical solution is attached
- x = 34, y = 23
It is easy to solve the system by substitution
- y = 57 - x
- 0.05x + 0.1(57 - x) = 4
- 0.05x + 5.7 - 0.1x = 4
- 0.1x - 0.05x = 5.7 - 4
- 0.05x = 1.7
- x = 1.7/0.05
- x = 34
Then the value of y is
- y = 57 - 34 = 23
As we see x > y, so Leila is right

How do we evaluate the veracity of Leila's assertion?
We can arrive at whether the statement is true or false by solving for the value of Y using the graphical method. Where Y is the amount of wheat and X is the amount of corn.
Our function is given as follows:
X + Y= 57. ..........1
Recall that the total amount of pasta is 57 grams
Recall as well that the total amount of protein in the pasta is given as:
0.05x + 0.1y= 4grams.......2
By inputting equations 1 and 2 into the Desmos Graph, we have x to be equal to = 34, and y = 23. (please see the attached image).
Recall that Leila's assertion was that there is more corn in the Pasta. Since x is the amount of corn, then Leila's assertion is True that: x>y.
The algebraic solution is arrived at using substitution.
Rewriting equation (1), we have
y = 57 - x .......................(3)
Let us substitute y into equation (2) above. That gives us:
0.05x + 0.1(57 - x) = 4.........................(4)
Expanding the brackets, we obtain
0.05x + 5.7 - 0.1x = 4
Collecting like terms, we can rewrite the quation as:
0.1x - 0.05x = 5.7 - 4
0.05x = 1.7
Rewriting the equation such that it is subject to x, we have
x = 1.7/0.05
x = 34
If from the above, x = 34, inputting that into equation (3) above, we have
y = 57 - 34; Therefore,
y = 23
