Solve the problem.A company that produces inflatable rafts has costs given by the function 
, where x is the number of inflatable rafts manufactured and C(x) is measured in dollars. The average cost to manufacture each inflatable raft is given by 
(x) = 
.What is the horizontal asymptote for the function 
? Describe what this means in practical terms.
A. y = 20; $20 is the least possible cost for producing each inflatable raft. B. y = 15,000; $15,000 is the least possible cost for running the company. C. y =15,000; 15,000 is the maximum number of inflatable rafts the company can produce. D. y = 20; 20 is the minimum number of inflatable rafts the company can produce.
