    Answer:

    initial value of phone is $ 60

    Step-by-step explanation:

    Step 1

    let  x = initial price of phone before reduction

    Step 2

    write a equation in x which models the condition

    after 20% reduction phone price is $ 48

    x- 0.2x = 48                                                   (1)                          

    Step 3

    solve the equation and answer the question

    x(1-0.2) = 48

    0.80x = 48

    we factor out x at the left side

    divide both side with 0.80 we get

    0.80x/ 0.80 = 48 /0.80

    x = 60

    we found that initial value of phone is $ 60

    Step 4

    we check the proposed solution into the original problem

    we apply the reduction to initial price which we computed in equation 1 put value of x we get

    60-0.20*60 = 60-12 = 48

    hence we got the same price that is $ 48 so solution is correct
