using gams solve the following:

A distribution center makes deliveries to 12 customers and has 2 options for making its daily deliveries. One option is to rent Isaku trucks with a maximum capacity of 2 deliveries per route and the other is to rent Kantore trucks with a maximum capacity of 4 deliveries per route. Isaku units have a rent cost of $60 per truck. The table in the excel file shows the distance in kms between the distribution center, node 1, and its customers. If the company wants to minimize the cost of renting the trucks plus the consumption of gasoline (directly proportional to the distance), what is the maximum that the company could pay for the rent of each Kantore truck in order to make it equally or more cost efficient than to use the Isaku trucks?

Note: (i) consider that one kilometer is covered with $1 of fuel. (ii) consider that the trucks should not return to the distribution center at the end of the route. (iii) consider node 1 as the distribution center.

The following points will be graded: a) scenario with two deliveries, b) scenario with 4 deliveries, c) answer to the question
