Quizplus · Accepted Answer

The total amount of money is the sum of the first 60 natural numbers: 1 + 2 + 3 + ... + 60. This sum can be calculated using the formula for the sum of an arithmetic series: n(n + 1)/2, where n is the number of terms. For 60 days, the sum is 60(60 + 1)/2 = 1830 cents, which is $18.30.
