Question 296158: I need help. I have no idea how to solve this word problem using the five step method. A new edition of a video game costs $60, but it's previous version only costs $40. If 15 games are sold for $840, how many copies of the newest game sold?

not a percentage or ratio problem but def an algebraic problem

a+b=15
a=15-b

a= previous version
b= new version
so
12 new versions and 3 previous versions
