Answer:
$60
Step-by-step explanation:
11 identical pairs of Air Jordan cost $660.
To find the cost of one pair, you have simply to divide the total amount paid by the total number of pairs.
Total amount paid = $660
Total number of pairs = 11
The cost of one pair
A has fixed one time fee of $12 and if you go to it say "m" months you pay $28 for each month, so your total cost at A is really 12 + 28m.
B has a fixed one time fee of $20 and if you go to it "m" months you pay $26 for each month, so you total cost at B is 20 + 26m.
how many months for the cost to be the same?
well, since the cost for both is the same, we can just get A's, knowing that B is the same
