Answer:each 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)

Answer:
each rest stop is 0.45 inches apart on the new map.
Step-by-step explanation:
First, we need to figure out how long is the highway. since 6/2 = 3, we know that the length of the highway is equal to 45*3. 45*3 = 135.
Now since the beginning stop doesn't count(it's at the 0 miles point and normal dividing would not count 0), so we know that there is 10 stops.
Since on the new map there was 30 miles in a inch, 135 miles on the new map would equal to 4.5 inches(135 = 120+15 = 4*30+0.5*30). 4.5/10 = 0.45 inches. So basically the rest stops are 0.45 inches apart.
Pure gold is 24 Karat's so the ratio of purity 18 karat gold is:
(Number of Karats of Gold chain)/(Number of Karats of pure Gold)
this will give us:
18/24
=3/4
The weight of pure gold in 18 Karat Gold will be:
(ratio of purity)×(Total weight of chain)
=3/4×18
=13 1/2 ounces
=13.5 ounces.
