Multiply both sides of the equation by 100p.

Subtract 30p form both sides of the equation.

Add 4000 to both sides of the equation.
Divide both sides of the equation by 70.

Our equation is {(100p - 4000)/ 100p}= 0.3
Multiply on both sides by 100p.
We get, {(100p - 4000)/ 100p} X 100p = 0.3 X 100p.
That is, 100p - 4000 = 30p (Since 0.3 X 100 = 30)
That is, 100p - 30p = 4000.
That is, 70p = 4000.
That is, p = 4000/70
That is, p = 57.14.
