Question

A frozen pizza is stored in a grocery store's freezer at - 6°C. During its transport home, its temperature rises 13°C. When the pizza is put in a home freezer, its temperature goes down 19°C. What is the temperature of the pizza in the home freezer?

A) 12° C
B) -12° C
C) 0° C
D) -38° C

Answer 1

at the start pizza has -6
the temperature rises 13 during the transport, so it should have -6+13=7
because the temperature goes down 19 when pizza is put in the home freezer, the final temperature should be 7-19=-12
so b is the correct answer
if the temperature rises -> +
if the temperature goes down -> -
