Answer:
Amount Charli paid for the car = $9,450
Step-by-step explanation:
Amount Carter paid for the car = $21,000
Sienna paid 75% of what Charli paid
Amount Sienna paid for the car = 75% of $21,000
= 75/100 * $21,000
= 0.75 * $21,000
= $15,750
Amount Sienna paid for the car = $15,750
Charli paid 60% of what Sienna paid
Amount Charli paid for the car = 60% of $15,750
= 60/100 * 15,750
= 0.60 * 15,750
= $9,450
Amount Charli paid for the car = $9,450
