Question 1053375: Here's my question:
Two publishers have offered Frank a deal on his new book "101 Smelly but Effective Cures for Athlete's Foot." The first has offered to pay him $20,000 up front and a $3 royalty for every book it sells. The second has offered to pay $15,000 up front and a $4.25 royalty for every book it sells. Over what range of sales will Frank make more from the deal with the second company than he will from the deal with the first?
I'm supposed to translate this word problem into an inequality and solve, but I don't know where to start or how to do it.

Let n be the amount of books sold. Then:
20000+3n<15000+4.25n
5000<1.25n; 4000 Frank will make more money with the second company as long as more than 4000 books are sold. ☺☺☺☺
