Kenny plans to mow lawns all summer, and then use the profits to buy video-games and books. He charges $[RATE] per lawn. The video-games are $[RATE] each. The books are $[RATE] each. At the end of the summer he has mowed [NUMBER] lawns. There are [NUMBER] video-games he really wants, and then he will use the rest for books. How many books can he buy?
Kenny earns $525 because 35 x 15 = <<35*15=525>>525
He spends $225 on video games because 5 x 45 = <<5*45=225>>225
He has $300 left because 525 - 225 = <<525-225=300>>300
He can buy 60 books because 300 / 5 = <<300/5=60>>60
