O win a contest, the number of beans in a jar has to be guessed within 20 of the actual number. If the number of beans in the ja
r is 645, which equation can be used to find the minimum and maximum number of beans that will win the contest, and what is the maximum guess that could win? |x – 645| = 20; maximum guess: 635 beans
|x – 645| = 20; maximum guess: 665 beans
|x – 20| = 645; maximum guess: 635 beans
|x – 20| = 645; maximum guess: 665 beans
