X = $ 10 dvd's.....y = $ 12 dvd's
x + y = 200....x = 200 - y
10x + 12y = 2200
10(200 - y) + 12y = 2200
2000 - 10y + 12y = 2200
-10y + 12y = 2200 - 2000
2y = 200
y = 200/2
y = 100 ....so there were 100 $ 12 dvd's sold
The equation is 114 = 1/3p - 3
To solve it:
117 = 1/3p
351=p

<u>Answer:</u>
He will order 72 pairs of high tops
<u>Explanation:</u>
Given the store owner sells two pairs of running shoes for each pair of high tops
For every pair of high tops, he sells 2 pairs of running shoes

Therefore, 144 pair of running shoes = 144/2 = 72 pairs of high tops
Therefore, he will order 72 pairs of high tops
