Question 1 TheBestEver company produces three types of trucks: small, mid, and heavy. The production of any type of truck requires three install operations. The following table shows the time required for each operation in minutes. The time needs for stamping is 30 minutes per hour. The time available for motor installation is 60 minutes per hour. The company has two stations for wiring and each of them is available for 45 minutes per hour. The profit made is $20 from each Small Truck, $30 from each Medium Truck, and $40 from each Heavy Truck. a. Define decision variables. Your definition must include unit size \& time frame. Kim's Kitchen Supply wants to extend its business and makes oil supply contracts with fried chicken restaurants in Newark. Kim's premium oil bottle has 3/4 gallon of olive oil and 1/4 gallon of canola oil while regular oil bottle has 2/3 of olive oil and 1/3 of canola oil.
