Acompany is expanding its building area from 19,000 square feet to 24,320 square feet. what is the percentage increase 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%.
