Question

Arnold puts a $139.00 coat on layaway. He is required to make a 25% deposit. How much will Arnold pay later to get his coat out of layaway?

Answer 1

Final payment is: `$104.25`

Explanation:

There are sat least 2 ways of calculating this. You put everything together in one go or can split the process. I am going to split it.

`color(blue)("Determine the deposit")`

The deposit is: `25/200xx$139.00 =$34.75`

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
`color(blue)("Determine the final payment")`

`$139.00`
`ul($color(white)(1)34.75) larr" subtract"`

Write as:
`$13cancel(9)^(8) .cancel(0)^(9)cancel(0)^(10)`
`ul($color(white)(1)3color(white)(.)4color(white)(.). color(white)(.)7color(white)(..)5) larr" subtract"`
`$104color(white)(..).color(white)(.)2color(white)(..)5`

Final payment is: `$104.25`
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
`color(red)("The other method")`

Let the final payment be `x`

`x=$139(100/100-25/100)`

`x=$139(75/100)=$104.25`
