What's the percent increase from 5 dollars to 8 dollars

Work Shown:

A = old value = 5

B = new value = 8

C = percent change

C = 100*(B - A)/A

C = 100*(8 - 5)/5

C = 100*(3/5)

C = 100*0.6

C = 60%

The fact that C is positive indicates we have a percent increase.

If we apply 60% to 5 then we have 0.60*5 = 3

So we've increased by $3 to go from 5 to 5+3 = 8.

y=1/4x-4
