Answer: the starting temperature is - 7 degrees.

Step-by-step explanation:

Let x represent the starting temperature.

Then the temperature doubled. It means that it became 2x degrees

Then the temperature dropped by 10 degrees. It means that it became 2x - 10 degrees.

Then the temperature increased by 40 degrees. It means that it became 2x - 10 + 40 = 2x + 30 degrees.

If the temperature is now 16 degrees, it means that

2x + 30 = 16

2x = 16 - 30

2x = - 14

x = - 14/2

x = - 7 degrees
