<h3>What is percentage increase?</h3>
percentage increase can be regarded as the
relative change and relative difference used in comparing two quantities.
The percentage increase can be calculated as;
[50/100] = [60/x]
if we cross products, we have
[50x]=[6000]
Then
x=120
Therefore, 60 is 120% of 50

No, it is not, a parabola, (from this equation, which is x^2, disregarding the +8 or y-intercept) cannot be a one-to-one function, it is a many-to-one.
Answer:
x + 4x + 1 = 76
Step-by-step explanation:
Let
x = Leon's amount
y = Laci's amount
"Laci has $1 more than 4 times Leon"
i.e y = 1 + 4x ----------------(1)
"together they have $76
i.e x + y = 76 ----------------(2)
if you take equation (1), and substitute for the value of y in equation (2):
equation (2) becomes:
x + (1 + 4x) = 76
or
x + 4x + 1 = 76 (answer)
