what is the opportunity cost (in civilian output) of a defense buildup that raises military spending from 4.0 to 4.3 percent of a $20 trillion economy?

So don't take my word i'm not exactly a mathematical person but i would assume a. because while selling the soap every month you increase in sells so you would by 11 percent. the you would get the factor 0.89 which if i had to guess would be the monthly profit over 11 probably wrong tho
