.36 dollars a day

100 days = 36 dollars

50 days = 18 dollars

25 days = 9 dollars

humm, no more common factors

25. The sum of a penny, a dime, and

a quarter is 36 cents. The number 36

factors into 2²•3². To get an integral

value in dollars, we must multiply by 5² so that the product ends in two zeroes.

Any multiple of 25 will work, but 25 is

the least of those values.
