To 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 jar 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?
A
|x – 645| = 20; maximum guess: 635 beansB
|x – 645| = 20; maximum guess: 665 beansC
|x – 20| = 645; maximum guess: 635 beansD
|x – 20| = 645; maximum guess: 665 beans
