Difficulty: Easy
Correct Answer: 8 %
Explanation:
Introduction / Context:
After an initial discount, further discounts apply to the already reduced price. To reach a specified final price, compute the required additional percentage on the reduced base, not on the original list price.
Given Data / Assumptions:
Concept / Approach:
If x is the additional discount rate, then 1,200 * (1 − x) = 1,104. Solve for x as a decimal or percent. Remember this x is on the reduced price of $1,200.
Step-by-Step Solution:
1,200 * (1 − x) = 1,104.1 − x = 1,104 / 1,200 = 0.92.x = 1 − 0.92 = 0.08 = 8%.
Verification / Alternative check:
Apply: 1,500 → 20% off → 1,200; then 8% off 1,200 → 1,200 * 0.92 = $1,104, which confirms the result exactly.
Why Other Options Are Wrong:
10%, 12%, or 15% would overshoot; 6% would not reduce far enough to $1,104.
Common Pitfalls:
Taking the second discount on the original list price. Successive discounts always apply to the current (already reduced) price.
Final Answer:
8 %
