Asked by Katelin

Mary's parents decided to give her an allowance every Saturday. The first Saturday they gave her $.01. For each successive week, they double the amount given the previous week. If Mary saves her allowance, in how many weeks will she be a millionare?
Answered by Emily
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.
