Answer: $160
Explanation:
Anne opened a savings account and put in $10.00.
Double = 2 times the amount.
Since the balance doubles each month:
1 month: $20.00 (10 x 2)
2 month: $40.00 (20 x 2)
3 month: $80.00 (40 x 2)
4 month: $160.00 (80 x 2)
Answer:
$160
You can set up an equation that will work for any time period, but since it is only 4 months we can do this simply too:
10 x 2 = 20
20 x 2 = 40
40 x 2 = 80
80 x 2 = 160
