Aperson saves €1 in the first month and decides to double the amount he saves the next month. he continues this pattern of saving twice the amount he saved the previous month for 12 months how much will he save on the 12th month and how much will he have saved in total for the year ignoring any interest he received?

(a)€2048

(b)€4095

Step-by-step explanation:

So the amount of money we would save at nth month is

where n = 1, 2, 3, 4, ...

At the 12th month, meaning n = 12, we would save

= €2048 for that month

The total amount we would save in a year is

1 + 2 + 4 + 8 + 16 + ... + 2048

= €4095

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

the square root of what number? if you add that, then someone will probably answer the question.
