Final answer:
Mrs. Zemaitatis was able to make 38 complete rolls of quarters when she divided her 1,542 quarters into rolls of 40 quarters each.
Step-by-step explanation:
The student question asks how many complete rolls of quarters Mrs. Zemaitatis can make with 1,542 quarters if one roll contains 40 quarters. To find this, we divide the total number of quarters by the number of quarters in one roll.
The calculation is: 1,542 quarters ÷ 40 quarters/roll = 38 full rolls with a remainder. Since we are only interested in complete rolls, we discard the remainder.
Therefore, Mrs. Zemaitatis was able to make 38 complete rolls of quarters.
