you spent the same ratio of your worth on an election as Perot did, how much money would you have spent?

Question

It was reported that Ross Perot spent approximately $40 million of his own money in the 1992 presidential campaign. His total worth was reported to be approximately $4 billion. If your total worth was $50,000 and you spent the same ratio of your worth on an election as Perot did, how much money would you have spent?

Answer 1

40 million/4 billion = 4*10⁷/4*10^⁹ = 1/100 = 5*10⁴/x

x = 5*10⁶ = 5 million
