A south dade farmer knows that the number of potatoes harvested varies directly with the number of potato plants grown. Last year the farmer harvested 189 potatoes from 9 potato plants. If the farmer plants 14 potato plants this year, how many potatoes can he expect to harvest?
First you divide 189 by 9 so you can find out how many the farmer harvested in one plant [tex]189 \div 9 = 21[/tex] Then you multiply 21 by 14 because 21 potatoes are harvested from one plant [tex]21 \times 14 = 294[/tex]
