The area of the figure is

as you should know, to get the inverse of any expression, we start off by doing a quick switcheroo on the variables and then solve for "y".

There are 16 ounces in a pound. If there are 4 pounds, then you take 16 and multiply it by 4 and then add 6.
The answer is: 70.
Since there are 9 hockey cards per page and it holds 900 hockey cards you can multiply 9 by 68 to get the total of 612 hockey cards.
