Julio predicted that the average high temperature for january would be -7 degrees celcius. the actual average high temperature was 4 degrees higher than julio’s prediction. which describes the actual average high temperature for january?

Julio predicted that the average high temperature would be -7 degrees celcius
The actual average temperature was 4 degrees higher than what Julio expected.

This means that, to get the actual average high temperature, we would add 4 to the temperature predicted by Julio as follow:
Actual average temperature = Julio's expectation + 4
Actual average temperature = -7 + 4 = -3 degrees celcius

She predicted the high temp would be -7. But the actual high temp was 4 degrees higher(-7 + 4) = -3 <== the actual high temp

The correct answer is $90
