Toby is selling plants to raise money for the gardening club. He buys plants for $4 each and sells them at the market for $6 each. If he sells 20 plants, how much money will he have earned for the club?
First, you find the profit that Toby is making by taking the cost of each plant and subtracting it from the selling price. Then, you multiply that by the amount of plants he sells.
