Lin bought 4 bags of apples. Each bag had the same number of apples. After eating 1 apple from each bag, she had 28 apples left.
What part of the story does x represent
The number of apples in each bag.
Let x represent the number of apples in each bag.
4x - 4 = 28
4x = 32
x = 8
Thus, x represents the number of apples in each bag, which is 8.
