1. The problem statement, all variables and given/known data Your budget is such that if you spend your entire income, you can afford either 4 units of good x and 6 units of good y OR 12 units of x and 2 units of y. A) What is the ratio of the price of x to the price of y? B) If you spend all your income on x, how much x could you buy? 2. Relevant equations Budget line: p1x1 + p2x2 = m m = income p1 = price of x p2 = price of y x1 = good x x2 = good y 3. The attempt at a solution The two budget lines (which are equal) will be: 4(p1) + 6(p2) = m 12(p1) + 2(p2) = m So would the ratio be 4/12 = 6/2 ? And I have no clue about B). Do I have to solve for anything? Using subsitution doesn't solve anything. I still up end up with variables.
