<human>:  Duke was at a garage sale when he spotted DVDs on sale. They were separated by price into 2 different boxes. In the first box, he found 10 movies that he wanted. These were $2.00 apiece. The second box was marked $5 each and he found 5 movies he wanted. What was the average price of each of the DVDs he bought?
<bot>: How much did Duke pay for the first box? ** In the first box he bought 10 DVDs at $2.00 each, so he paid 10*2 = $<<10*2=20.00>>20.00
How much did Duke pay for the second box? ** In the second box he bought 5 DVDs at $5.00 each, so he paid 5*5 = $<<5*5=25.00>>25.00
How many DVDs did Duke buy? ** He bought 10+5 = <<10+5=15>>15 DVDs
How much did Duke spend? ** He spent $20 + $25 = $<<20+25=45.00>>45.00
What was the average price of each of the DVDs he bought? ** The average price of each DVD is $45/15 = $<<45/15=3.00>>3.00 each
