<human>:  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?
<bot>: How many total bags of chips do the students buy? ** The students buy 2*5=<<2*5=10>>10 bags of chips.
How much will the bags of chips all cost? ** 10 bags of chips cost 10*0.5=<<10*0.5=5>>5 dollars.
How much will the candy bars all cost? ** 5 candy bars cost 5*2=<<5*2=10>>10 dollars.
How much money will the students need in total? ** They will need 10+5=<<10+5=15>>15 dollars.
