A contractor, Susan Meyer, has to haul gravel to three building sites. She can purchase as much as 18 tons at a gravel pit in the north
of the city and 14 tons at one in the south. She needs 10, 5, and 10 tons at sites 1, 2, and 3, respectively. The purchase price per ton
at each gravel pit and the hauling cost per ton are given in the table below. Susan wishes to determine how much to haul from each pit
to each site to minimize the total cost for purchasing and hauling gravel.
Hauling Cost per Ton at Site
Pit
1
3
Price per Ton
North
$30
$60
$50
$100
South
$60
$30
$40
$120
Now suppose that trucks (and their drivers) need to be hired to do the hauling, where each truck can only be used to haul gravel from
a single pit to a single site. Each truck can haul 5 tons, and the cost per truck is five times the hauling cost per ton given above. Only
full trucks would be used to supply each site.
a. Formulate this problem as an assignment problem by constructing the appropriate cost table,…
Dr. Davidson is comparing the cost of buying ball caps with the Duluth emblem from two different companies. Company A charges a $50 fee plus $7 per cap. Company B charges a $30 fee plus $9 per cap. Show all appropriate work.
An assistant is in charge of ordering lunch for the monthly office meeting. For the first month, she
orders ten Falafel wraps, twenty-five Turkey BLT sandwiches, and fifteen hot Ham and Swiss paninis for a
total of $361.25. The next month, she orders fifteen Falafel wraps, thirteen Turkey BLT sandwiches,
and twenty-two hot Ham and Swiss paninis for a total of $342.50. For the third month, she orders eight
Falafel wraps, twenty-two Turkey BLT sandwiches, and twenty hot Ham and Swiss paninis for a total of
$359. How much does each sandwich cost?
Falafel Wrap = $
Turkey BLT = $
Hot Ham and Swiss = $
