To find the single equivalent discount to two successive discounts of 8% and 12%, we need to use the formula for successive discounts. When two discounts of \(x\%\) and \(y\%\) are given, the equivalent single discount \(D%\) can be calculated using the formula:
\(D = x + y - \left(\frac{x \cdot y}{100}\right)\)
Given the discounts are 8% and 12%, let's substitute these values into the formula:
\(D = 8 + 12 - \left(\frac{8 \cdot 12}{100}\right)\)
Calculate each part step-by-step:
Therefore, the single equivalent discount for the two successive discounts of 8% and 12% is 19.04%.
Thus, the correct answer is 19.04%.
