Suppose that you own a $1-$year bond with a $10\%$ coupon rate, a yield of $2\%,$ and a face value of $$1,000.$ Suppose further that you took out a $1-$year loan of $$900$ at $2\%($you lucky devil, you!$)$ to help start your new food truck business. Calculate your net worth $($assets minus liabilities$)$ if all interest rates rise from $2\%$ to $3\%.\_\_\_\_\_\_\_\_\_\_\_$
