Question

The price of a wireless phone increased by 14% to $165. What was the original price to the nearest dollar?

Answer 1

If the original prize was x then what happened was that

114%x=165

or

`(114)/(100)`x=165

so we have to mupliply both sides by 100:

114x=16500

and divide by 114:

x=
`(16500)/(114)`=
`(8250)/(57)`=144
`(42)/(57)`
