35. The average low temperature for a 4-day period in January for the city of
Orlando, Florida, was 58°F. After the fifth day, the 5-day average was 59°F.
What was the low temperature on the fifth day?
F. 59°F
G. 60°F
H. 61.5°F
J. 63°F

Answer 1

To find the low temperature on the fifth day, we need to determine the total temperature for the 5-day period and subtract the total temperature for the first 4 days.

The total temperature for the 5-day period is the average temperature (59°F) multiplied by the number of days (5):

Total temperature = 59°F * 5 = 295°F

The total temperature for the first 4 days is the average temperature (58°F) multiplied by the number of days (4):

Total temperature for first 4 days = 58°F * 4 = 232°F

Now, we can find the temperature on the fifth day by subtracting the total temperature for the first 4 days from the total temperature for the 5-day period:

Temperature on the fifth day = Total temperature - Total temperature for first 4 days

Temperature on the fifth day = 295°F - 232°F

Temperature on the fifth day = 63°F

Therefore, the low temperature on the fifth day was 63°F. The answer is J.
