FLO inc. is a company in the culinary field that sells 2 types of frozen Chinese appetizers, namely Bakpao and Dim Sum. To produce 1 pack of Bakpao it takes 0.2 kg of chicken meat, while for 1 pack of Dim Sum it takes 0.25 kg. The time spent in making 1 pack of Bakpao is 2 hours while for Dim Sum is 3 hours. The demand for the two products varies per month, but the average is 110 packs of Bakpao and 180 packs of Dim Sum. The selling price of the Bakpao and Dim Sum is Rp. 33,000 for Bakpao and Rp. 66,000 for Dim Sum per pack. To optimize business operations, Flo inc. has set several goals that have been sorted by priority: 1. Sell as much as possible so that the sales target for both products is achieved, which is at least Rp. 13.200.000 per month 2. Utilization of the entire production capacity of 660 hours per month 3. Limit the use of the main raw material (chicken) to no more than 45 kg per month 4. Limit overtime hours to 300 hours per month 5. The demand for each product is met, but because the price is twice as high, the demand for Dim Sum is prioritized over Bakpao. From the information above: a.
