Use your costs and recommendation retail prices to write a linear programming model to show possible profits for selling certain numbers of each type of candle. Decide on the constraints for the number of candles made for the sale and explain your reasoning for these constraints. Graph the feasible region and find maximum and minimum profits. It costs $1.60 to make each candle and you earn $2.40 per candle. They are made in batches of 8x8 each. The dimensions for each candle is 6x6x8 cm. Minimum of 3 batches, maximum of 8.
