Celestila Moonn lives in Russia and expects to earn $50,000$ Ruble $($RUB$)$ this year and would like to spend RUB $45,000$ on current consumption $($she plans to save the remaining RUB$5,000).$ Unexpectedly, Moonn gets an opportunity to invest RUB$10,000$ in a project that will repay RUB$13,000$ in one year.

If the current interest rate is $10\%,$ should Moonn take this investment even though she had planned to save only RUB$5,000.$
