antoniya [11.8K]

Answer:

x = 100

Step-by-step explanation:

If you save one penny on January 1, two pennies on January 2, three pennies on January 3, and continue this pattern for one year
monitta
The given condition is an arithmetic sequence with the first term (a1) is 1 penny and the common difference (d) is 1 penny. A year that is not a leap year has 365 days (n). The arithmetic series (S) is calculated through formula,
 
                               S = (n/2) (2a1 + (n - 1) x d)

Substituting the known values,
 
                               S = (365/2) (2 x 1 + (365 - 1) x 1)
 
                               S = 66795 pennies

A dollar is 100 pennies. Therefore, at the end of the year, the total savings is $667.95.
