Joyce bought each of her 7 nephews a DVD of the movie "Iron Man 3"
or a Blu-Ray disc of the movie "The Hunger Games". Each DVD cost
$14.95 and each Blu-Ray disc cost $16.88 she spent a total of 114.30,
how many of each did she buy?

Let x = the number of DVDs of "Iron Man".

Then the number of Blu-Ray discs = 7-x

Equation:

14.95x + 16.88(7-x) = 114.30

Solve that for x, the number of DVD's.  Subtract from 7 to find
the number of Blu-Ray discs.
