bryan berg built an 83-story 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 100-story house of cards?
Let's set up a proportion and let x = the number of cards need for a 100-story house.
83/27,000 = 100/x
83x = 2,700,000
x = 32,530.1205 = 32,531
