changing variable cells. Adjust the number of units produced by each supplier using the

following constraints:

a$.$ Set the total number of virtual assistants produced as greater than or equal to

$11,000,$ DIG Technology's minimum production goal.

b$.$ Set the total cost to be less than or equal to $925,000,$ the maximum total cost

DIG Technology wants to spend.

c$.$ Set the number of virtual assistant units produced by each supplier to be less than

or equal to $4000$ to balance the production among the suppliers. Also, make sure

that this same range contains integers since DIG Technology cannot sell a fraction

of a product.

d$.$ Run Solver, keep the solution, and then return to the Solver Parameters dialog

box. Save the model in the range A$14$:A$21.$
