To find the fraction of the total apples picked that were sold as fresh fruit, we need to find the fraction of apples that were not discarded or made into cider.
If Sara discarded 1/10 of the apples, then 9/10 of the apples remaining were not discarded.
From these remaining apples, 300 were made into cider.
Therefore, the fraction of apples that were sold as fresh fruit is:
(9/10) - (300/total apples)
Since we do not know the total number of apples picked, we cannot determine the exact fraction. The correct response is "not enough information."
The town of Oak Manor measures 3.8 miles by 4.2 miles. Solve for the total area.(1 point)

To find the total area of the town of Oak Manor, we multiply the length and width of the town.
The length of the town is 3.8 miles and the width is 4.2 miles.
So, the total area is:
Area = length x width
Area = 3.8 miles x 4.2 miles
Area = 15.96 square miles
Therefore, the correct response is "15.96 mi^2" or "15.96 square miles."
is it "15.96 mi^2" or "15.96 square miles."
Both "15.96 mi^2" and "15.96 square miles" are correct ways to represent the total area of Oak Manor. They both convey the same information.

To find the diver's elevation when they are 23% of the way down, we need to calculate 23% of 97.2 feet.
23% of 97.2 feet is:
(23/100) x 97.2 feet = 22.356 feet
Since the diver is descending, the elevation will be negative. Therefore, the correct response is "−22.356 ft." or "negative 22.356 ft."
