Nick had 14 jelly beans in a bag. His mother put a handful of jelly beans in the bag. When Nick counts his jelly beans, he discovers he now has 28 of them. Which of the following equations will help Nick solve for the number of jelly beans, j, that his mom put in the bag? 14j = 28
14 + 28 = j
14 + j = 28
j − 14 = 28
