Two projects have equal net present values when calculated using a $8\%$ annual effective interest rate. Project $1$ requires an investment of $$19,000$ immediately and will return $$8,000$ at the end of one year and $$14,000$ at the end of two years. Project $2$ requires investments of $$9,500$ immediately and $X in two years. It will return $$4,000$ at the end of one year and $$11,000$ at the end of three years. Find the difference in the net present values of the two projects if they are calculated using a $7\%$ annual effective interest rate. $($Round your answer to the nearest cent.$)$
