Ming has a budget of $100/month to spend on high-tech at-home entertainment. There are only two goods that he considers: games and movies. For each of the situations described below, draw Ming's budget constraint. Denote the axes as x= games per month and y= movies per month. Label the x and y intercepts of the budget constraints, the slopes, and any kink points (that is, give the quantities associated with the intercepts, slopes, and kinks.) 1) Games cost $12 each and movies are $4 each. (This is a standard budget constraint.) 2) Movies cost $4 each. Games cost $12 each for the first three; however, if more than three games are purchased, the price for additional games (that is, for the fourth, fifth, etc. ) drops to $8. 3) Movies cost $4 each. The price of games is $12 for up to three games but drops to $10 per game if more than three are purchased. 4) Movies cost $4 each. Games can be bought for $12 each or in groups of three for $30 for the three. 5) Games cost $12 each and movies are $4 each. However, for $24 Ming can purchase a subscription that allows him to watch 10 movies in a month; for more than 10 movies, the cost returns to $4 each. He is allowed to purchase only one subscription per month.
