Question

The sales os HiTop sneakers rose from $3 million to $3.4 million. How do you find the percent increase to the nearest whole percent?

Answer 1

I got `13%`

Explanation:

You know that the increase was:

`3.4-3=$0.4`million

we need to compare this, in terms of `%`, with the value of `$3` million that we can consider as `100%`. So we get using fractions:

`(100%)/(x%)=3/0.4`

rearranging:
`x%=100%*0.4/3=13%` that represents our percentual increase.
