The function f(x) = 5x² + 40x is a parabola. Then the vertex of the parabola will be at (–4, –80).
<h3>What is the parabola?</h3>
It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.
The function f(x) = 5x² + 40x
Then add and subtract 80, then we have
f(x) = 5x² + 40x + 80 – 80
f(x) = 5(x² + 8x + 16) – 80
f(x) = 5(x + 4)² – 80
The vertex of the parabola will be at (–4, –80).

There's on 38000 there? is it meant to be 380000?
Originally without the 10% extra, both have 100%. since the question stated that the first salesperson have 10% more, the percentage of his paycheck will be a total of 110%. on the other hand, the second salesperson will have only 100%. the question then stated that when both oaychecks are added together, it will give a total of $1075.
110% + 100% represents $1075
210% represents $1075
so now you need to find what is 1 %
1% represents $(1075/210)
the first salesperson have 110%, so you
(1075/210) × 110% = $563. 0952381
round off to the nearest cent so it will become $563.10
the first salesperson paycheck is $563.10
the second salesperson paycheck 100%. so you....
(1075/210) × 100% = $511.9047619
=$511.90
therefore the second salesperson paycheck is $511.90.
