Mrs. Lim got 68 gallons - 18 gallons = 50 gallons this morning. So she was able to get a total of 68 gallons + 82 gallons + 50 gallons = 200 gallons. She was able to sell 200 gallons - 24 gallons = 176 gallons. Thus, her total revenue for the milk is $3.50 / gallon x 176 gallons = $616.
The answer: 616

The answer: 300

Reasoning and answer: First, we need to determine the profit per book. To do this, we perform 20 - 5 = 15 dollars in profit per book. Next, we divide the total sales by the profit per book, performing 120 / 15 = 8 books sold in total. Since the books are sold 2 at a time, we divide the number sold by 2 to find the total number of people sold to, performing 8 / 2 = 4 people in total.
The answer: 4
