Question

After a 40% price reduction, an exercise machine sold for $564. What was the exercise machines prince before this reduction?

Answer 1

let
x--------> the exercise machines prince before the reduction
y--------> the exercise machines prince after the reduction

we know that
y=$
`564`


`y=x*[100-40]/100 \\ y=x*0.60 \\ x=y/0.60 \\ x=564/0.60 \\ x=940`

the answer is
$
`940`
