I'm not sure what the answer is, but I think I might know how you will be able to figure it out. Take the \$.01 Mary got the first week and double it to get what she got the second week (\$.02). Then multiply the \$.02 by 2 to get what she got the third week (\$.04) Progress- ivly do that until you get \$1,000,000.

THis question is from the Abeka 7th grade math book p. 175 #17.
