To find the marginal productivity of labor, we need to take the partial derivative of the production function with respect to labor, which in this case is the variable x.

∂Q/∂x = 11e^(9y-49x) * (-49)

Substituting x = 80 and y = 5, we get:

∂Q/∂x = 11e^(9(5)-49(80)) * (-49) = 25.39

Therefore, the marginal productivity of labor is 25.39 crates per hour when the number of hours is 80 and the number of acres is 5.
