Final answer:
Elizabeth can round up to the nearest number divisible by 4, which is 24, to estimate that each of the 4 bags will contain about 6 apples.
Step-by-step explanation:
Elizabeth wants to estimate how many apples will be in each of her 4 bags, given she picked a total of 23 apples. A good estimate for an easily divisible number by 4 would be to round the total number of apples to the nearest number that is divisible by 4. Since 24 is the closest number to 23 that is divisible by 4, Elizabeth can estimate that each bag would contain about 6 apples, which is the result of dividing 24 by 4.
