Come up with a question and reasoning that would justify this answer: 2400
The question is: Oula and Tona work for a delivery service company, supplying different parts of their state with milk products. They are paid $100 for each delivery made in a day. In a particular month, Oula made 96 deliveries while Tona made 3/4 times as many deliveries as Oula. Calculate their difference in pay that month.
Step-by-step reasoning process: Oula's earnings for that month are 96 * $100 = $9600. Tona made 3 / 4 * 96 = 72 deliveries that month. Tona's total earnings for that month are 72 * $100 = $7200. Their difference in pay is $9600 - $7200 = $2400.
