You can put this solution on YOUR website! On day 1, there are 2^0 pennies. On day 2, there are 2^1 pennies. And so on. So basically, on day a, there are pennies. So we need to find the smallest integer a such as . 2^6 is 64 and 2^7 is 128. If a-1 is 7, than on day 8, there is more than $1.00 worth of pennies.
