Snack A provides 10 grams of protein and costs 2 dollars, snack B provides 6 grams of protein and costs 3 dollars. You need at least 30 grams of protein a day. Let x be the number of snack A you buy and y be the number of snack B you buy. You want to minimize cost. State the linear programming problem in mathematical terms, identifying the objective function and constraints. Do not solve the problem to completion. Just state the inequalities needed and the objective function.
