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?
The students buy 2*5=<T>multiply(2, 5)=10 bags of chips.
10 bags of chips cost 10*0.5=<T>multiply(10, 0.5)=5.0 dollars.
5 candy bars cost 5*2=<T>multiply(5, 2)=10 dollars.
They will need 10+5=<T>add(10, 5)=15 dollars.
