We are given 
total number of DVDs=85
price of each DVDs=$19
we have to find total amount of money 
total amount of money = (total number of DVDs)*(price of each DVDs)
total amount of money =85*19
total amount of money =$1615
now, we know that 1615 is more close to 1600 than 1700 because both are nearest hundredth 
so, 
total amount of money is $1600.........Answer
