Please provide solution of b part of my previous question related to R code

A food factory makes three types of cereals, A,B and C, from a mix of several ingredients: Oates, Apricots, Coconuts and Hazelnuts. The cereals are packaged in 1 kg boxes. The following table provides details of the sales price per box of cereals and the production cost per ton (1000kg) of cereals respectively. The following table provides the purchase price per ton of ingredients and the maximum availability of the ingredients in tons respectively. The minimum daily demand (in boxes) for each cereal and the proportion of the Oates, Apricots, Coconut and Hazelnuts in each cereal is detailed in the following table, a) Let xij0 be a decision variable that denotes the number of kg of ingredient i, where i could be Oates, Apricots, Coconuts, Hazelnuts, used to produce Cereal j, here j is one of A,B,C, (in boxes). Formulate an LP model to determine the optimal production mix of cereals and the associated amounts of ingredients that maximises the profit, while satisfying the constraints. [20 Marks] b) Solve the model in R/R Studio. Find the optimal profit and optimal values of the decision variables
