He works 5 days a week and takes care of one different garden each day. How many hours will he need to work if he wants to earn at least $250 a week? 
Write an inequality for the total number of hours he needs to work. Solve the inequality and check your answer.
 I know it $20(5)+ $10(3 hrs)= $250.

$20(5)+ $10h > $250 100 + 10h > 250 10h > 150 h > 150/10 h >= 15
