The snack machine at Richmond High School sells candy bars for $2 each and chips for $.50 each. How much money, in dollars, will 5 students need in total if each of them gets 1 candy bar and 2 bags of chips? Let's be accurate as possible.
The students buy 2 * 5 = 10 bags of chips. 10 bags of chips cost 10 * 0.5 = 5 dollars. 5 candy bars cost 5 * 2 = 10 dollars. They will need 10 + 5 = 15 dollars.
The answer: 15.
