The first thing you need to understand is that Celsius is always smaller than Fahrenheit but for converting
Celsius to Fahrenheit= 9/5C) + 32 = F.
When converting Fahrenheit to Celsius
=(5/9F) - 32 = C.
Celsius to Fahrenheit= 9/5C) + 32 = F.

The accurate general rule is
"double the Celsius temperature, subtract 10%, and add 32°".
So A is probably the closest in the general case. The other choices may be valid in certain specific cases.

A.) 22+22=44+30=74
B.) 22+22+22=66+30=96
C.) 22+22+22=66-10=56
D.) 22+52=74
so it's narrowed down to A
and D. Do you still think it's A?

My thought process is A for sure. But D seems like a better choices. Now I'm confused your thoughts??

I'm not absolutely sure but an average pill is 1mg so I would have to say a strand of hair weighs 2mg.
