Tammy has 10 orange trees from which she can pick 12 oranges each day. Tammy sells 6-packs of oranges for $2. How much money will Tammy have earned after 3 weeks if she sells all her oranges? Let's be accurate as possible.
User
Tammy picks 10 trees x 12 oranges / tree = 120 oranges per day. Tammy sells 120 oranges / day / 6 oranges / pack = 20 6 - packs of oranges a day. Tammy sells 20 packs / day x 7 days / week = 140 6 - packs a week. In 3 weeks Tammy sells 140 packs / week x 3 weeks = 420 6 - packs. Tammy makes 420 packs x $2 / pack = $840.
The answer: 840.
