To crosstrain its data scientists on multiple programming techniques, DataVista plans to offer a

three$-$day workshop on SQL and a four$-$day workshop on Python. 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 DataVista

must contract with them for at least $12$ workshops. The cost to DataVista is $$500$ for each SQL

workshop and $$400$ for each Python 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.
