1.) Each assumption leads to different aspects of the battle to achieve higher arms.  Assumption A wants to increase the level of arms to a proportion of the arms level of the other country.  To do this, you want to take the rate of growth of the other country and multiply this by a proportional co ....

....  only one time.  First-Order means nothing is squared, cubed, etc., and a difference equation adds or subtracts certain levels of need. 
2.) DX(n) = b1 Y(n-1) - a1 X(n-1) + c
DY(n) = b2 X(n-1) - a2 Y(n-1) + d
Use these equations to represent the change in billions of dollars spent on national arms where 1£ n £10 and
