Question

The weather for March in Toronto, Canada, can be extremely unpredictable. On one Tuesday, the temperature at 6:00 a.m. was -10 degrees Celsius (°C). By 2:00 p.m., the temperature had increased by 15°C. At 5:00 p.m., as the Sun started to set, the temperature dropped by 7°C.

Which of the following shows the correct change in temperature?

Answer 1

I think that the answer should be B because it shows an increase of 15 degrees celcius. You can count three dashes since each dash is worth five degrees. Then you can notice that the the mark goes to the right. Since it decreases by 7, it goes more to the the left.
