Christopher recently won $20,000 in the lottery and decides to save his money in a unique way. He saves $1.00 on the day after he won the lottery. He then saves twice as much as he did the previous day for a total period of two weeks. How much does Christopher have saved by the end of this time period?

Question

wait, after the day he won the lottery he saves twice more for the next week, right?
My question is, is it that he save the next week altogether twice more than the first day, or is that for a period of a week he saves (each day) twice more than the previous day (giving a geometric sequence with a common ratio of 2) ?

yes the first question you asked

solomonzelman · Answer

you mean the first side of the question. SO he saves the first day 1$, and then the next 2 weeks he saves 2$ altogether. like that ?

solomonzelman · Answer

So, he saves altogether, 1+2. which gives 3 dollars.
