Question

a television on sale for 1/4 off original price. Original price is 120 more then sale price. What is original price of tv

Answer 1

Original Price = 160

Sale Price =40

Explanation:

Let Original Price be x and Sale Price be y

y=1/4 of x (Equation 1)

x=120+y (Equation 2)

Put value of x from equation 2 in equation 1

y= (1/4)*(120+y)

y=120/4 + y/4

y-y/4=30

3y/4=30

y=30*4/3

y=40

Put value of y in Equation 2

x=120+40

x=160
