How much money did Kenny make? ** He made $150 selling the cards because 100 + 50 = <<100+50=150>>150
How many cards did Kenny sell? ** He sold 100 cards because 150 / 1.5 = <<150/1.5=100>>100
How many cards did Kenny sell? ** The cards he sold were 2/3 of his collection because 1 - (1/3) = 2/3
How many cards did Kenny start with? ** He started with 150 cards because 100 / (2/3) = <<100/(2/3)=150>>150
