a penny a day

First of all: It'll be a lot of pennys!

calculate a penny to a jar for each day of the year Jan 1 one, Jan 2 2 etc to Dec 31 365

If you mean: 1p, 2p, 3p, 4p, for Jan. 1, 2, 3, 4.......etc., then at the end of the year you will have:

(365 X 366) / 2=66,795 pennies or: 66,795/100=$667.95 dollars.

I like his answer better . . .
