Question

If you save three pennies on January 1, six pennies on January 2, nine

pennies on January 3, and continue this pattern for one year (not a leap year),
what will be the value of your entire savings, in dollars, at the end of that one
year? Express your answer as a decimal.

Answer 1

The value at the end of the first year is $10.95.

Answer 2

2003.85

Explanation:

365/2 * (3 + 1095) = 200385.

1 Dollar = 100 pennies

200385 pennies/100 = 2003.85

so you have $2003.85 in your account on the 365th day.

hope this helps :-)
