Solution

Step 1 :Suppose you go to a company that pays $0.03 for the first day, $0.06 for the second day, $0.12 for the third day, and so on. If the daily wage keeps doubling, what will your total income be for working 31 days?

Step 2 :We can solve this problem by using the formula for the sum of a geometric progression. The first term \(a\) is $0.03, the common ratio \(r\) is 2, and the number of terms \(n\) is 31.

Step 3 :The formula for the sum \(S\) of a geometric progression is \(S = a \cdot \frac{r^n - 1}{r - 1}\).

Step 4 :Substituting the given values into the formula, we get \(S = 0.03 \cdot \frac{2^{31} - 1}{2 - 1}\).

Step 5 :Calculating the above expression, we find that the total income for working 31 days will be \(\boxed{64424509.41}\) dollars.
