MSI can do both day and evening interviews with the following costs per interview:
In addition, the following quota guidelines are required by the client:
1- Interview at least 300 evening interviews
2- At least 40% of the day interviews must be from households with children.
MSI should now determine the best household, time-of-day interview plan that minimizes interview costs. Develop a spreadsheet and find the optimal number of interviews of each type.
