a store owner buys a lot of 1,000 necklaces for 120.00. If she sells each necklace at 160 what is the minimum number of necklaces she has to sell to make a profit

Answer 1

just one necklace sold would bring a profit of $40. ($160-$120)

Or maybe you meant she bought a lot of 1000 necklaces for $120 each.

She paid $120,000 for 1000 necklaces. then she needs to recoup $120,000 to break even.

$120,000/$160 = 750 necklaces

751 necklaces sold would bring a profit of $160

750 x 160 = 120,000-120,000=0 profit

751 x160 = 120,160-120,00= $160 profit
