You can put this solution on YOUR website!
Set up a formula that expresses the situation. 3+1.25n=10 where n is the number of additional hours.

\n" ); document.write( "Solve it for that n, and then add 1 to n because n is only the number of additional hours after the first.

\n" ); document.write( "3+1.25n=10 ---> 1.25n = 7 ---> n = 5.6. 5.6+1 = 6.6. But the problem doesn't indicate you can pay for part of an hour, so round down to 6 hours.
