Human: Ms. Jones got thank you cards from 30% of her class. 1/3 of these contained a gift card for $10. If she got $50 in gift cards, how many students were in her class? Assistant: 
How many gift cards did Ms. Jones get? ** She got 5 gift cards because 50 / 10 = <<50/10=5>>5
How many thank you cards did Ms. Jones get? ** She got 15 thank you cards because 5 / (1/3) = <<5/(1/3)=15>>15
How many students were in Ms. Jones' class? ** She has 50 students because 15 / .3 = <<15/.3=50>>50
