Answer:
dC = 2.44
Relative error = 19%
Step-by-step explanation:

Δv = 3 ; ΔT = 1 , v = 23, T = 8
Use differential Calculus


Relative Error
dC / C @(T = 8, v=23) * 100 = 19 %
If you put it into the slope intercept from (x1,y1) and (x2,y2)
then subtract 3-8 and 2-5 you should get 5\3 as your answer.
I'm guessing 99.65
1800+10%-20%-25%=99.65
but it probably wrong
