    let the scarves be x and the hats be y

    4x + 6y = 52 ... equ (1)

    1 + x = y

    y - x = 1 ... equ (2)

    multiplying equation 2 by 4

    4y - 4x = 4

    adding equation 1 and 2

    10y = 56

    ∴y = 5.6 dollars

    substituting the value of y into equation 2

    5.6 - x = 1

    ∴x = 4.6 dollars
