Last week Sara’s income was $12 a week. The price of popcorn was $3 a bag, and the price of a smoothie was $3.e. Draw a graph of Sara’s budget line with the quantity of smoothies on the x-axis.f. What is the slope of Sara’s budget line? What determines its value?
Alex distributes his monthly income of $600
between two goods, movies and food. By
spending his entire income on movies, he can
enjoy a maximum of 20 movies. On the other
hand, by spending his entire income on food he
can consume a total of 60 units of food. Assume
that food consumption is measured along the
horizontal axis and the consumption of movies is
measured on the vertical axis. Calculate the slope
of Alex's budget line when the price of food
increases to $20 while the price of movie remains
unchanged.
