The rate they receive can affect their working speed.For example, supose they can work for either $9.00 per hour or for $320 plus $3 for each hour less than 40 if they complete the job in less that 40 hours. Suppose the job will take t hours. If t is greater than or equal to 40 the hourly rate is better. If t<40, for what values of t is the hourly rate the better pay scale? </SPAN>\n" );
