Question

The temperature started at 39°F. If the temperature went down 5°F and then up 7°F, whats is the temperature difference relative to the low temperature?

A) -7°F
B) -5°F
C) 5°F
D) 7°F

Answer 1

Explanation - 7°F

39 + (-5) + 7 = 39 - 5 + 7 = 41

then, the low was 39 + (-5) = 34

thus, 41 - 34 = 7

so, 7°F above the low of 34°F

Answer 2

The answer is D 7 degrees F
