    Answer:

    He sold 10 hangers and 10 neclesses

    Step-by-step explanation:

    Given data

    Let the number of door hanger be x

    and the number of neckless be y

    so

    x+y= 20———1

    also,

    2.25x+3.75y= 60———2

    Solve 1 and 2 together

    From 1

    x= 20-y

    put this in place of x in 2

    2.25(20-y)+3.75y= 60

    45-2.25y+3.75y= 60

    1.5y= 60-45

    1.5y= 15

    y= 15/1.5

    y= 10

    Put y= 10 in 1

    x+10= 20

    x= 20-10

    x= 10
