hello i need help solving this problem thank you!

a block it follow that TS T in This ex ? You are given : ( J(t ) = 283 + 8t for OstEl 24 + 86 2+ 16 But 2 is the effective interest rate of year one That corresponds to S(.). Fund X accumulates w/ simple interest of annual rate ? Fund y accumulates according to SC. ). (V An amount . 2 is depoisted in each Fundy and Fund y at time too At what time ( so is Ax(t) - Ayle) maximized? A X C. and AY ( , ) are the amount functions for the finds X o Y, respectively
