Final answer:
The dealer's net price for all five 2012 Mini Cooper S vehicles with a 30/20/15 chain discount is calculated by applying each discount successively to the starting retail price. After all discounts, the net price per vehicle is $11,995.20, leading to a total of $59,976 for five vehicles.
Step-by-step explanation:
To calculate the dealer’s net price for all five 2012 Mini Cooper S vehicles with a 30/20/15 chain discount, we first need to understand what a chain discount is. A chain discount is a series of discounts applied successively to the list price of an item.
The retail price of one Mini Cooper S is $25,200. Applying the first discount of 30%, we get:
$25,200 × (1 - 0.30) = $25,200 × 0.70 = $17,640
Now, we apply the second discount of 20% on the new price:
$17,640 × (1 - 0.20) = $17,640 × 0.80 = $14,112
Lastly, we apply the third discount of 15%:
$14,112 × (1 - 0.15) = $14,112 × 0.85 = $11,995.20
To find the total net price for five vehicles, we multiply the net price of one vehicle by five:
$11,995.20 × 5 = $59,976
Therefore, the dealer's net price for all five Mini Cooper S vehicles is $59,976.
