His utility function is given by U(X,Y)=X(Y+1)2 You are also told that his marginal utilities are MUX=(Y+1)2MUY=2X(Y+1) 7. Find the optimal consumption bundle of good X and Y (Point A) 8. Find total utility of this consumer at the optimal consumption bundle 9. Because of Corona pandemic, the price of good X has doubled. Find the substitution effect (SE) of good X.is Hint: use only one decimal number 10. What is the income effect, and the relationship between the two products
