Consider the budget constraint between "spending today" on the horizontal axis and "spending a year from today" on the vertical axis. Suppose that you have $100 today and expect to receive $100 one year from today. Your money market account pays an annual interest rate of 25%, and you may borrow money at that interest rate. Suppose now that the interest rate increases to 40%. What happens to the slope of your budget constraint relative to when the interest rate was 25%? The slope
