I went to Sam's club today to buy engine oil and they had two options. One liter bottles and four liter bottles. I only care about the total quantity of engine oil I buy. Let X stand for the quantity of one liter bottles and Y for the quantity of four liter bottles. Suppose that the price of one liter bottles of oil is $10 and the price of four liter bottles is $30. If I have $60 to spend on engine oil how many one liter bottles and how many four liter bottles will I buy? For simplicity assume that I can buy parts of a bottle Question 3 options: X=3, Y=1 X=1.5, Y=1.5 X=6; Y=0 X=0; Y=2
