Question

Julio predicted that the average high temperature for January would be -7°C. The actual average high temperature was 4 degrees higher than Julio’s prediction. Which describes the actual average high temperature for January?

A)–11°C

B)–3°C

C)3°C

D)11°C

Answer 1

Average temperature was 4 degrees higher means "+4",
so -7+4=-3
Answer C)

Answer 2

The correct answer is B. The actual average high temperature for January is -3ºC.

Explanation:

When we talk about temperatures in negative Celcius degrees (that is, below zero, which is the freezing point in this temperature scale), each temperature increase implies an approach to zero. Therefore, an increase of 4 degrees from -7ºC would reach a temperature of -3ºC, that is, numerically it would lower 4 levels, approaching 0.
