Susan reading 1 page every three minutes is a unit rate. Thus, simply multiply any number of pages by 3 to get the times. For example, for Susan to read 281 pages, it would take 281*3 minutes.
the answer is yes when you add the same number to each side the inequality is still true. If u subtract then the inequality would not be true because you are taking away from both of the sides which will make the answer smaller. GOT IT ???
