Explanation Given Information: The numbers of payments are 18 and payments made are 5 . Formula used: Follow the steps to compute the rebate fraction: Sum-of-the-digits formula is computed through the formula: Sum-of-the-digits = n ( n + 1 ) 2 Where n represents the number of payment. Compute the rebate fraction as follows: Rebate fraction = Sum of the digits of the number of remaining payments sum of the digits of the total number of payments Calculation: Consider numbers of payments are 18 and payments made are 5 . Compute the remaining payments by subtracting payment made from total payments. Payment Remaining = 18 − 5 = 13 Hence, the payments remaining are 13 . Compute the sum-of-the-digits of the number of remaining payments using the sum-of-digit formula. Substitute n = 13 , Sum-of-the-digits = n ( n + 1 ) 2 = 13 ( 13 + 1 ) 2 = 91 Hence, the sum-of-the-digits of the number of remaining payments are 91
