After multiplying by 1.23, what is the next operation?

• A. Subtract each calculation
• B. Add each calculation together
• C. Multiply the results again by 1.23
• D. Divide by the number of values

Answer: (B)

After scaling each value by 1.23, the next step is to combine the scaled results into a single figure by adding them together. This aggregates the adjusted values into a total. Re-applying the factor by multiplying again would distort the total by over-scaling. Dividing by the number of values would give an average, not the total, unless that was the explicit goal. Subtracting isn’t indicated here either. For example, with values a, b, and c, the adjusted amounts are 1.23a, 1.23b, and 1.23c, and adding them gives 1.23(a + b + c).
