Answer:
Option D -17.5 degrees is correct answer
Step-by-step explanation:
Since a calendar week has 7 days. and temperature is falling by -2.5 daily.
So, On Day 1 Temperature is -2.5 degrees
On Day 2 Temperature is -2.5 + -2.5 = -5 degrees
On Day 3 Temperature is = -5 + -2.5 = -7.5 degrees
On Day 4 Temperature is = -7.5 + -2.5 = -10 degrees
On Day 5 Temperature is = -10 + -2.5 = -12.5 degrees
On Day 6 Temperature is = -12.5 + -2.5 = -15 degrees
On Day 7 Temperature is = -15 + -2.5 = -17.5 degrees
So, Option D -17.5 degrees is correct answer.
