a company is expanding its building area from 17,500 square feet to 21,175 square feet. what is the percentage increase of the area of the building space?

Let's make an equation.

19,000x=24,320

This equation shows the percentage increase, which is x. Once we have x, we need to subtract 1 from it since in the equation the 1 shows that it's increeasing. All we need to do is divide both sides by 19,000.

24,320÷19,000

1,28-1=0.28; we need to multiply by 100 to find the increase.

0.28×100=28

So, the percentage increase is 28%.

what graph

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
