Find dy/dx using implicit differentiation ln(20+e^xy)=y

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.

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
