Don is a sales representative for a car dealer company. He earns $850 plus 5% on every car he sells. His usual fortnight expense is $795. In one fortnight he sold one car for $25000 and another for $50000. How much did he save that fortnight.

Answer 1

Don earned $25000 * 5/100 = $<<25000*5/100=1250>>1250 for selling the first car.
Don earned $50000 * 5/100 = $<<50000*5/100=2500>>2500 for selling the second car.
So, Don's total earning for that fortnight is $2500 + $1250 + $850 = $<<2500+1250+850=4600>>4600.
Don's expenses for that fortnight is $795.
Therefore, Don saved $4600 - $795 = $<<4600-795=3805>>3805. Answer: \boxed{3805}.
