bryan berg built an 83story house of cards in 1995. he used 27,000 playing cards to accomplish this feat. at this same rate, about how many cards would it take to build a 100story house of cards?

Let's set up a proportion and let x = the number of cards need for a 100story house.
83/27,000 = 100/x
Cross multiply:
83x = 2,700,000
x = 32,530.1205 = 32,531
