marty saves $1 the first day of a month, $2 the second day, $4 the third day. he continues to double his savings each day. find the amount that he will save by the 15th day. How do I solve this?
Simple... !,2,4,8,16,32,64,128,256,512,1024,2048,4096,8192,16384. He would have saved $16,384 by day 15. Just double each number as you go. Hope this helps!!
