You can put this solution on YOUR website! he gives 416 speeches per year.
832000 people show up in his speech every year,and gets 12480000 dollars each year.
renting cost 5824000 per year
meals,suppport personnel 4420000 dollars each week.
he makes 12,480,000-4,420,000-5,824,000=2,236,000 net profit yearly if he travells 52 weeks.
equation is
earning=8n*2000*15 -8n*14000-85000*n where n is the number of weeks
can you solve
129000=n(43000)
n=3 weeks
