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

1 answer:

8 0

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
$ $940$
