5 DVDs - $70
1 DVD - $14

Since 2 DVDs cost $28, we now need to find the cost of 1 DVD. We put this is in a linear order.

#$28=2 DVDs#
#$x = 1 DVD#

Now cross multiply the two equations

#28 =2x#
#x = 28/2#
#x = 14#

Thus Nate buys a DVD at the rate of $14

We then repeat the procedure to find the cost for 5 DVDs

#$14 = 1 DVD#
#$x = 5 DVDs#

Cross multiply

#x = $70#

Thus 5 DVDs cost $70
