Question

What is 25% of ($)22?

Explanation:

`25/100*$22`

`550/100`

`=$5.5`

Answer 2

`$5.50`

Explanation:

To solve this problem, turn it into an equation. Here are some tips to remember:

1. "Is" means "equals", so wherever you see "is", use a `=` sign.
2. "Of" means "multiplication", so use a `xx` sign when you see that word.
3. `25%` is the same as `25/100` as a fraction, or `0.25` as a decimal. I'm going to use the fraction form in the equation.
4. Use variables for the things you do not know. I will use the variable `x`.

`stackrel(x)overbrace"What"stackrel(=)overbrace"is"stackrel(25/100)overbrace"25%"stackrel(xx)overbrace"of"stackrel(22)overbrace"22"`

`x = 25/100 xx 22`

`x = 25/100 xx 22/1`

`uarr`anything over 1 is itself, so putting 22 over 1 does not change it's value

`x = (25 xx 22)/(100 xx 1)`

`x = 550/100`

`x = 5.5`

`$5.50` is `25%` of `$22`.
