1. Joan is on summer break and spends most of her time either playing video games or browsing the internet. Her utility function is U(g1, 92) = 3992q$, where q1 represents the hours spent browsing the internet and q2 hours playing video games. Joan does not have a budget constraint but she has 15 hours to spend on both activities. (a) Write the equation for one of Joan's indifference curves when the level of utility is equal to 100. (b) Write Joan's time constraint. (c) Find the amount of hours that Joan will spend on each activity that maximizes her utility and satisfies her time constraint. Use either the substitution or Lagrangian method. (d) Can Joan afford any bundle that yields a utility of 50? Explain. (e) How does Joan's optimum amount of time spent on each activity change if her utility function is U (q1, 92) = 5ln(3) + In(q1) + 4ln(q2)?

Joan is on summer break and spends most of her time either playing video games
or browsing the internet. Her utility function is U(g1, 92) = 3992q$, where q1 represents the
hours spent browsing the internet and q2 hours playing video games. Joan does not have a budget
constraint but she has 15 hours to spend on both activities.
(a)
Write the equation for one of Joan's indifference curves when the level of utility is
equal to 100.
(b)
Write Joan's time constraint.
(c)
Find the amount of hours that Joan will spend on each activity that maximizes her
utility and satisfies her time constraint. Use either the substitution or Lagrangian method.
(d)
Can Joan afford any bundle that yields a utility of 50? Explain.
(e)
How does Joan's optimum amount of time spent on each activity change if her
utility function is U (q1, 92) = 5ln(3) + In(q1) + 4ln(q2)?
