document.write( "Question 1154478: A concert manager counted 700 ticket receipts the day after a concert. The price for a student ticket was $11.50, and the price for an adult ticket was $18.00. The register confirms that $10,812.50 was taken in. How many student tickets and adult tickets were sold? \n" ); document.write( "

document.write( "ANSWER.  425 adult tickets, and the rest, 700-425 = 275 student tickets.\r\n" );
