To crosstrain its data scientists on multiple programming techniques, SciConcepts plans to offer a three-day workshop on Python and a four-day workshop on SQL. The chief data scientist has requested that at least four of each type of workshop be offered during the current quarter. The consultant that provides these workshops has 42 days available during this quarter, and SciConcepts must contract with them for at least 12 workshops. The cost to SciConcepts is $500 for each Python workshop and $400 for each SQL workshop. Formulate a linear programming model that can be used to determine the cost-minimizing number of each type of workshop to offer this quarter. Solve the LP using the graphical solution method.
