Given the word problem, we can deduce the following information:
1. Amelia bought a new car with a sticker price of $9,987.
2. She paid 4% sales tax, traded in her old car for $1,950, and made a 25% down payment.
To determine the total amount of the purchase that she financed, we multiply the price of the car by the sales tax first:
Sale price = $9,987 (1.04) = $10,386.48
Next, we deduct the amount of the trade-in car:
$10,386.48-$1,950=$8,436.48
Then, we get the 25% down payment:
$8,436.48 (0.25)= $2,109.12
Now, to compute for the total amount of the purchase price:
Purchased Price Financed = $8,436.48-$2,109.12 = $6,327.36
Therefore, the answer is c. $6,327.36.
