Answer:
$22,500
Explanation:
Chance of getting low quality car = 50%
Chance of getting high quality car = 50%
Cost of low quality car = $15,000
Cost of high quality car = $30,000
So, Price of the car = 50% of lower quality + 50% of higher quality
= (50% × $15,000) + (50% ×30,000)
= $7,500 + $15,000
= $22,500
Hence, price of the used car will be $22,500.
