You can put this solution on YOUR website!
Let x = 30 minute (or part of) work period after the first 30 minutes.
\n" ); document.write( "Then the job will cost $27 + $18x, depending on how long the job lasts.
\n" ); document.write( "You need to keep the job under (or less than) $100, so your equation would be:
\n" ); document.write( "27 + 18x < 100. Now solve for x:
\n" ); document.write( "Subtract 27 from both sides to get:
\n" ); document.write( "18x < 73.
\n" ); document.write( "Divide both sides by 18 to solve for x to get:
\n" ); document.write( "x < 73/18, or x < 4.0555, but x has to be a whole number, so the first whole number less that this is 4.
\n" ); document.write( "So, how long did the technician work?
\n" ); document.write( "The first half hour at $27 dollars UP TO 4 more half hour segments. The problem did not ask for what is the most amount of time could be worked, it only says that the job cost less than $100. So the answer could be:
\n" ); document.write( "1 hour,
\n" ); document.write( "1 ½ hours,
\n" ); document.write( "2 hours,
\n" ); document.write( "2 ½ hours, or
