A constraint with a positive slack value:. a. will have a positive dual price.
b. will have a negitive dual price.
c. will have a dual price of zero.

c. will have a dual price of zero.

Explanation:

When solving a linear equation with constraint that means not a balanced equation, we introduce a slack variable that is almost equal to zero, in order to balance the equation.

In that case the slack variable can have positive or negative value depending upon equation, but it does equal to almost zero.

Thus, it can have dual shadow value almost equal to zero, as the value is not considered.

1: b     the use of non-standard grammar

2: c     strong and willful.

its correct i took the test have a nice day: )

in 2001, dell computer became the world’s largest personal computer vendor, continuing to

gain market share and post profits in an industry struggling with slumping sales and billions of

dollars in losses. dell sells 90% of its pcs directly to the final customer, largely bypassing the

reseller channel that accounts for most of the world’s pc sales. this direct customer relationship

is the key to dell’s business model, and provides distinct advantages over the indirect sales

model. dell’s direct relationship with the customer allows it to tailor its offerings to customer

needs, offer add-on products and services, and use the internet to offer a variety of customer

services. in addition, dell’s pcs are built to customers’ specifications upon receipt of an order,

giving dell additional advantages over indirect pc vendors who must try to forecast demand and

ship products based on those forecasts. dell’s direct sales and build-to-order model has achieved

superior performance in the pc industry in terms of inventory turnover, reduced overhead, cash

conversion, and return on investment (kraemer, et al., 2000).
