1. Click6, I can give you an intuitive answer but not a mathematical one.
My intuitive answer is there are 100 oranges bought in this problem. Thus each orange cost .30 or 100*.30=\$30 The sellng price per orange is .35 or 5 cents more than the cost. 80 sold oranges times .35 equals \$28 which fits with the stated parameters of your problem.
