Answer: The correct answer is a) Noah gains $1,000 of value, and Emily gains $3,000 of value
Explanation:
The gain to each person will be based on the value on the car.
Noah valued his car for $10000 and sold it for $11000. To him is gain is $1000 which is an increase in the value.
However, Emily's value on the same car is $14000. Since she purchased the car for $11000, she has made a gain/ savings of $3000.
