RADIO X sells cheap radios for commercial use by buying surplus supplies

RADIO X sells cheap radios for commercial use by buying surplus supplies. A surplus bag of 100 diodes costs $2.00. A surplus bag of diodes, on average, has 10% faulty diodes (the faulty diodes are thrown away, and the remaining diodes are used in production). It takes 5 diodes to make 1 circuit board. If it takes 3 circuit boards to make a radio, how much money is needed to buy diodes to make x number of radios, in dollars?
