A store sells apples in two sizes: small and large. The store sold a total of 150 apples in one day. The number of small apples sold was twice the number of large apples sold. If the store makes $1.50 from each small apple and $2.00 from each large apple, how much total revenue did the store earn from selling apples that day? Let's think step by step and output the final answer within \boxed{}.
