Question

At his most recent medical checkup, a boy was 40 inches tall. Currently, he is 46 inches tall. What percent taller is the boy now?

im not smart at this lol

Answer 1

15%

Explanation:

`Percent of change =(new -old)/( old) *100\\`

The boy was 40 inches tall so that means 40 inches is the old value

The boy is currently 46 inches tall now, so 46 is the new value

Plug these values into the equation:

`Percent of change =(46 -40)/( 40) *100\\`

Simplify:

`Percent of change =(6)/( 40) *100\\`

`Percent of change =(600)/( 40) \\`

`Percent of change =15`

I hope this answers your question :)
