Vicky records the low temperature for three consecutive days. between the first and second days the temperature increased 6 degrees. between the second and third days the temperature decreased 3 degrees. on the third day the low temperature was –6º. what was the low temperature on the first day?

The low temperature on the first day was -9 degrees

Explanation:
To solve this problem we can work backwards. Since the low temperature on they third day was -6, we start with that number. Between the second and third day it decreased 3, so we want to do the opposite of subtracting and add 3 to -6, which is -3. Now we have the low temperature on the second day, -3. Next, between the first and second day the temperature increased by 6, so the opposite of adding is subtracting. We subtract -3 by 6, which gives us -9.

A: 0.26 would be the answer
