I know I have to make 3 equations

Question 148701: I need some help with the following word problem...
A small firm produces both AM and AM/FM ca radios. The AM radios take 15 hours to produce, and the AM/FM radios take 20 hours to produce. The Number of production hours is limited to 300 hours per week. The plant's capacity is limited to a total of 18 radios per week, and existing orders require that at least 4 AM radios and at least 3 AM/FM radios be produced per week. Write a system of inequalities representing this situation. In this case let x= AM Radios and y= AM/FM radios.
Would it be 15x + 20y (less than or equal to) 300 ???
