a weaver spends $420 on supplies to make wall hangings and plans to sell the wall hangings for $80 each.
a. write an inequality that gives the possible numbers of (w) wall hangings the weaver needs to sell in order for the profit to be positive
b. what are the possible numbers of wall hangings the weaver needs to sell in order for the profit to be positive

    a. $80 ea, w = number of wall hangings
    $420 total spent

    80w > 420

    b. w > 5.25
    she can't sell .25 of a hanging so,
    she would have to sell 6 for a positive profit of $60. (6 @ 80 ex = 480,
    480 - 420 = 60)

    I am not a tutor.
