What is the percent increase from $5 to $8 rounded to the nearest percent

For this case we can make the following rule of three:
5 $ ----------------------> 100%
$ 8 ----------------------> x
From here, we clear the value of x.
We have then:
[tex] x = (\frac{8}{5}) * (100)x = 160 [/tex] Therefore, the percentage of growth is given by:
[tex] 160 - 100 = 60 [/tex] Answer:
the percent increase from $ 5 to $ 8 rounded to the nearest percent is:
60%

When 5 is increased to 8, the increase is exactly 60 percent,with no rounding necessary.(The increase is 3, and 3 is exactly 60% of the original 5 .)
