Tom opened a lemonade stand to earn money to buy a new bike for $200. he sells a cup of lemonade for $1.00. on the first day he sold 8 cups of lemonade, on the second day he sold 16 cups and on the third day he sol 32 cups. if tom keeps selling cups of lemonade this way on what day will he have a total of $200.

1 - 8

2 - 16

3 - 32

x - +200

Each lemonade has a profit of $1, so the number of cups of lemonade he sells is the same as the amount of dollars he has. You just need to add each previous day's total to the next day's, doubling the amount of cups from the previous day's for each new day.

4 - (32 x 2 = ) 64

8 + 16 + 32 + 64 = 120. We need at least $80 dollars more, so we continue.

5 - (64 x 2 = ) 128

120 + 128 = $248.00 That's more than enough, so Tom will have enough money for his bike after the fifth day of selling lemonade.
