negative 169 and startfraction 13 over 24 endfraction
negative 121 and startfraction 7 over 24 endfraction
negative 12 and startfraction 1 over 24 endfraction
12 and startfraction 1 over 24 endfraction

Evaluate the following expression 1/3^2

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
