Expert Solution & Answer
Chapter 7, Problem 75RE
Solution
To calculate: The number of vehicles of each type are needed to deliver all of these.
The numbers are 2 minivans, 4 vans, and 2 trucks
Given Information:
Hix's Discount Electronics has three sizes of high-definition televisions (HDTVs) on sale: small (19-in.), medium (32-in.), and large (47-in.). Hix's has three types of vehicles that they use for deliveries: minivans, vans, and trucks. The minivans can carry 8 small, 3 medium, and 2 large HDTVs; the vans, 15 small, 10 medium, and 6 large; the trucks, 22 small, 20 medium, and 5 large. On the last day of the sale, Hix's has 115 small, 85 medium, and 35 large HDTVs to deliver.
Calculation:
Consider the given information,
Suppose that x is representing number of minivans, and y is number of vans z is representing number of trucks.?
Set up the equations. Considering the small HDTVs, there are 115 on the last day of sale:
Considering the medium HDTVs, there are 85 on the last day of sale:
Considering the large HDTVs, there are 35 on the last day of sale:
Write the system of matrix
And,
Therefore, the required numbers are 2 minivans, 4 vans, and 2 trucks.
