An analyst at a motor manufacturing company wants to evaluate the relationship between the cost each year to operate an electric motor and its hours of operation. He collects this data on 100 random motors produced by the company. The number of hours of operation has a mean of 3.9, and the cost has a mean of 52.6 dollars. A regression was fitted to the data, and it was found that for every hour increase in operation, the cost increases by $0.39. Predict the cost of operating the electric motor for 4.2 hours. Do not round your answer.
