The manufacturer wants to limit total shipping costs to exactly $29,900. How many cars should be sent from each plant to each dealer

Answer 1

Answer:

Total transportation cost = 23,750

Explanation:

We can calculate how many cars should be sent from each plant to each dealer  as follows

DATA

Plant 1 cars = 74

Plant 2 cars = 70

Demand

Dealer A needs 79 cars

dealer B needs 65

Shipping costs are

$300 per car from plant I to dealer A,

$130 per car from plant I to dealer B,

$180 per car from plant II to dealer A

$160 per car from plant II to dealer B.

limit total shipping costs to exactly $29,900

Start from the cheapest

$130 per car from plant I to dealer B.

$130 x 65 = 8,450

$180 per car from plant II to dealer A

$180 x 70 = 12,600

$300 per car from plant I to dealer A,

$300 x 9 = 2700

Total transportation cost = 8,450 + 12,600 + 2700

Total transportation cost = 23,750
