The hard drive on your computer has a capacity of 160 gigabytes (GB). You have used 122 GB. You want to save some home videos to your hard drive. What are the possible sizes of the home video collection you can save? If u represents the amount of space used, write an inequality that determines a, the amount of space available.

A. at most 282 GB; a ≤ 160 + u
B. at least 38 GB; a ≥ 160 − u
C. at most 38 GB; a ≤ 160 − u
D. at least 282 GB; a ≥ 160 + u

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
