525/2 is the answer to your question. which may be a little bit of a larger fraction than normal
So out of 100 questioned 71 said Dallas Cowboys , that means 71% did , now we have to work out 71% of 1200 which is 852
The slope is 5/1 and the y-intercept is -3
Let 
. Then
and substituting these into the ODE gives
Let 
, so that 
. Then the ODE is linear in 
, with
Multiply both sides by 
, so that the left side can be condensed as the derivative of a product:
Integrating both sides and solving for 
gives
Integrate again to solve for 
:
and finally, solve for 
by multiplying both sides by 
:
already accounts for the term in this solution, so the other independent solution is 
.
