To find the range of Fahrenheit temperatures, we can simply plug in the minimum and maximum Celsius temperatures into the formula and convert:
C = 5(F-32)/9
-15 = 5(F-32)/9
-135 = 5F - 160
25 = 5F
F = 5
Thus, the minimum Fahrenheit temperature is F = 5°F.
Similarly, we can find the maximum Fahrenheit temperature:
C = 5(F-32)/9
45 = 5(F-32)/9
405 = 5F - 160
565 = 5F
F = 113
Thus, the maximum Fahrenheit temperature is F = 113°F.
Therefore, the range of Fahrenheit temperatures is from 5°F to 113°F, inclusive, which gives us choice A as the correct answer.
