11. Set up the rational work application problem. Shelby and Mary started a beading business to make mask lanyards. If they work together they can make 5 lanyards in 40
mins. Mary can make 5 lanyards in 70 mins if she works alone. How would you set up
the equation to solve for how long will it take for Shelby to make 5 lanyards by herself?

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x

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.

Sole the equation 6n + 9 = -3n - 21 - 6 for n
