4. (15 points) Since 1979, low-income recipients have been given food stamps without charge. However, before 1979, people bought food stamps at a subsidized rate. For example, to get $1 worth of food stamps, a household paid about $0.20 (the exact amount varied by household characteristics and other factors). Assume the individual has income of $70.00 per month. Illustrate on a well anno- tated graph the budget constraint facing an individual if that individual may buy up to $50.00 per month in food stamps at $0.20 per each $1 coupon? Compare this con- straint to the original budget constraint with no assistance and the budget constraint if the individual receives $50.00 of food stamps for free.
