Bob loans his sister-in-law $1000 so she can make her rent. She must pay it back after one year. If Bob charges her 6 percent interest and wants to get a real return (real interest) of 3.5 percent, Bob must anticipate that inflation will be percent over the next year. (Carefully follow all numeric instructions. Enter your answer "as a percent, but without the percentage sign." In other words, if you think Bob predicts 99.99 percent inflation, just enter 99.99 in the blank.)
