The viewer mistakenly determined that one of the equations in the system should be 2 x + y = 28. Instead modifications should have been made before applying the equation.
<h3>What is an Equation ?</h3>
An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.
Total Questions = 20
Total Points = 28
Correct Answers = +2 points
Incorrect Answers = -1 point
The viewer represents the correct answers with x and the incorrect ones with y.
x+y = 20
for every correct answers 2 points;
and for every incorrect answers, -1 point
This can be written as
2x-y = 28
The viewer's mistake is that; instead of subtracting total incorrect points from the correct points, the viewer added them together;
now
2x-y = 28
x+y = 20
On adding the equations
]3x = 48
x = 16
y = 4
This means that the contestant answered 16 questions correctly and 4 questions incorrectly
The viewer mistakenly determined that one of the equations in the system should be 2 x + y = 28.

Answer:
Hello there!
The answer to your question is :
<em>C: Finn needs 6 cups of sugar for 4 cakes.</em>
<em>D: Finn needs 1 1/2 cups of sugar for 1 cak</em>e.
Step-by-step explanation:
The graph clearly shows ( sides cups of sugar) (bottom number of cakes)
For sugar you need 6 cups to make 4 cakes
For sugar on the second question you need 1 1/2 cups of sugar to make 1 cake
Multiply 1 1/2 times 6 then divide and your answer is 4. That's 4 cakes out of 6 cups of sugar out of the original cups of sugar ( 1 1/2)
This is the confirmed answer I took the quiz and got 100%
Hopes this helps you!
