Variable -word problem: At a temperature of 22 degrees C your device measures 0.13 el

[Coenie777]

First post and I hope this is the right place. My math knowledge is that slim ?

You are given the following information:

At a temperature of 22 degrees C your device measures 0.13 electrons/sec
I need to know what that 0.13 would be at 0 degrees if we assume it will remain linear.
One other factor to also satisfy is that for every 5.5 degrees increase in temperature, the value at 0 degrees would double. I guess you can then also assume that your answer would half for every decrease in that temperature below 0 degrees.

I would really appreciate it if someone can try and solve this and if possible provide an explanation of the reasoning behind it. What type of math question would this be classes as?

You are given the following information:

I need to know what that 0.13 would be at 0 degrees if we assume it will remain linear.

If what will remain linear? What is the relationship you are proposing?

One other factor to also satisfy is that for every 5.5 degrees increase in temperature, the value at 0 degrees would double.

The value of what would double at the fixed value of zero degrees?

Please reply with the full and exact text of the exercise, the complete instructions, and a clear listing of your thoughts and efforts so far, so we can try to figure out what is going on. Thank you!

Thanks for the reply.

I have no problem that I need to resolve in the sense that I was given this by someone. I am trying to figure out what a temperature dependent variable would be at 0 degrees centigrade.

I only have the following:

- At 22 degrees it records 0.13 electrons
- I want to know what it would record at 0 degrees. How many electrons (should be less then)
- Another conditions given is that for every 5.5 degrees increase in temperature above zero, the value will double. From zero to 22 take 4 5.5 degree changes. Thus the amount for 0 degrees in number of electrons need to satisfy the condition that it would be 22 degree C if we double it 4 times.

The only other condition I have is that it is a linear function. The electrons plotted against temperature will results in a linear line.

Is it possible to work with the limited amount of information given?
