Question

What is the 15% service tip on a $25.50 dinner in?

Answer 1

The tip would $3.83 rounding to the nearest penny.

Explanation:

This question is asking what is 15% of $25.50.

"Percent" or "%" means "out of 100" or "per 100", Therefore 15% can be written as `15/100`.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the number we are looking for "n".

Putting this altogether we can write this equation and solve for `n` while keeping the equation balanced:

`n = 15/100 xx $25.50`

`n = ($382.50)/100`

`n = $3.825` or `$3.83` rounding to the nearest penny.
