The correct answer is 120≤x+2y. This is because Jeramy earned at least $120, so the total amount of money he earned from selling books and toys should be at least $120. The total amount of money earned from selling x books is x*1 = x dollars, and the total amount of money earned from selling y toys is y*2 = 2y dollars. So the total amount of money earned is x+2y. Therefore, the inequality representing the possible combinations of toys and books he sold is 120≤x+2y.
