document.write( "Question 829803: On the first day of a recent coin drive, Mr.Li's AP class collected a total of 17.90. When he looked in the box, he found only quarters, dimes, and nickels. If there were 1/2 as many nickels as quarters, and 10 more dimes than nickels, how many of each coin did Mr. Li's class collect? \n" ); document.write( "
