**Reiny**, Saturday, December 31, 2011 at 11:27ameach album costs $7 and you buy x of them

cost of albums = 7x

each movie costs $8 and you have you have y of them

cost of movies = 8y

total cost is has to be less than $47

---> 7x + 8y < 47

sketch the graph of 7x + 8y = 47 , a straight line, and shade in the region below that line. Of course you would stay in the first quadrant, (x > 0, and y >0 , since you can't have negative number of movies and albums)

Since you can't buy partial albums and movies, both x and y have to be whole numbers.

So for solutions you would consider only ordered pairs that have whole numbers as their components.

e.g. (2, 2) or (1,5)
