Question

If 15% of the customer's total is $22.05, then the customer's total is _______."

Answer 1

$147

Explanation:

15% over 100 is .15

So you get .15x= 22.05

Get x by itself by dividing .15 by .15

whatever you do to one side you have to do to the other so divide 22.05 by .15 and you get $147

Answer 2

let's say is "x", so "x" is then 100% of the whole bill.

we know 15% is 22.05, what is "x"?

`\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 22.05&15\\ x&100 \end{array}\implies \cfrac{22.05}{x}=\cfrac{15}{100}\implies 2205=15x \\\\\\ \cfrac{2205}{15}=x\implies 147=x`
