Can this be explained in detail, as far as how I approach this question to how to solve and what formulas were used

Chris and Jen decide to go apple picking at a local apple orchard. As the number of apples they pick increases the cost of the apples also increases. The function f relates the varying cost of Chris and Jen's apples, c, in terms of the varying number of pounds of apples that Chris and Jen pick, n , where c = f(n) and f is defined by f(n) = 0.An + 7. Which of the following describes the meaning of f (24) ? Not enough information O The cost of each apple when 24 apples have been picked The number of pounds of apples Chris and Jen picked when the total cost is 24 dollars O The cost of 24 pounds of apples None of the above Evaluate f (24) f ' ( 24 ) = Preview Determine the rule for the function f -1 f -1 ( c ) = Preview Licen Points possible: 1 Unlimited attempts.
