33 - 2x
If this answer is incorrect, then I am sorry.
There are 52 weeks in a year. In order to figure out how much you have to save each week to save a total of $2000, you have to divide $2000 by 52.
2000÷52= 38.462
So to save $2000 you would have to set aside about $38.50 each week.
To return back to -18°C from -10°C, you would have to lower the temperature by -8°C to compensate for the difference.
Hope that helps!
