Final answer:
To find the total number of sheet sets, convert each fraction of a dozen to the number of sheet sets and add them up. The result is 917 sheet sets.
Step-by-step explanation:
The question requires adding up different fractions of dozens of sheet sets. First, let's convert each fraction to the number of sheet sets by multiplying each fraction of a dozen by 12, which is the number of units in a dozen.
- 19 1/2 dozen of twin sheet sets is 19.5 x 12 = 234 sheet sets.
- 33 2/3 dozen of queen sheet sets is 33.67 x 12 = 404 sheet sets (rounded to two decimal places).
- 23 1/4 dozen king sheet sets is 23.25 x 12 = 279 sheet sets.
Now, add up the total number of sheet sets:
234 (twin) + 404 (queen) + 279 (king) = 917 sheet sets
Therefore, the total number of sheet sets received is 917, which corresponds to option b.
