Solve the problem.
-Joey borrows $2,400 from his grandfather and pays the money back in monthly payments of $200.
a. Write a linear function that represents the remaining money owed L(x) after x months.
b. Evaluate L(10) and interpret the meaning in the context of this problem.
A) L(x) = 200x + 2,400; L(10) = 4,400, This represents the amount Joey has paid his grandfather after 10 months.
B) L(x) = -200x + 2,400; L(10) = 400, This represents the amount Joey still owes his grandfather after 10 months.
C) L(x) = -200x + 2,400; L(10) = 400, This represents the amount Joey has paid his grandfather after 10 months.
D) L(x) = 200x + 2,400; L(10) = 4,400, This represents the amount Joey still owes his grandfather after 10 months.

The correct linear function is L(x) = -200x + 2,400, which represents the remaining money owed after x months. After 10 months, Joey owes $400, indicating he has paid $2,000 of the $2,400 borrowed.
