Identify Total Cost:  Identify the total cost before the discount. Nora paid $78 after a $12 discount, so add back the discount to find the original cost. Calculation: 78 + 12 = 90. Determine Regular Cost:  Determine the regular cost per month. Divide the total cost by the number of months in the subscription. Calculation: 90 / 6 = 15. Formulate Equation:  Formulate the equation. The original monthly cost times the number of months minus the discount should equal the amount paid. Equation: 6m - 12 = 78.
