Quizplus · Accepted Answer

To find the list price, we need to work backwards from the net cost. The net cost of $7 is after two successive discounts of 30% and 15%. Let's denote the list price as $P$.First, the item is discounted by 30%, so it sells for 70% of its list price: $0.70P$.Then, it's discounted again by 15%, so it sells for 85% of the already discounted price: $0.85 \times 0.70P$.We know this equals $7: $0.85 \times 0.70P = 7$.Solving for $P$, we get: $P = \frac{7}{0.85 \times 0.70} = \frac{7}{0.595} \approx 11.76$.Therefore, the list price is approximately $11.76.
