He ordered three types of pizza, cheese, pepperoni, and supreme, the cheese cost 9$ each, pepperoni cost 12$ each, and supreme cost 15$ each. He spent exactly twice as much money on the pepperoni pizza as he did the cheese pizza. If the person spent a total of 420$ how much was each type of pizza </SPAN>\n" );
