財管題目，求解😭😭😭

@ 今天,小陳正在慶祝她的 40 歲生日。她的願望是希望在 65 歲退休時,退休後 的 20 年間,每年生日時都能從儲著帳戶中提出$240,000。第一次提款時間是她 的 66 歲生日。小陳打算參加兆豐銀行零存整付專案 (年利率 2%) ,每年生日 時都存入一筆等額現金到此專案帳戶 ,做為退休基金之用。 (1) 如果小陳從 40 歲開始存款,一直到 65 歲 (最後一筆存款是 65 歲生日) ,請問 她每年要存入多少錢才能支應她的退休需求 ? (可先找出以下條件:預計幾年後 退休 ? 退休後每年可領金額 ? 退休儲蓄金可使用年限? ) (2) 假設小陳剛剛很幸運地中了大樂透,所以她決定要改變計畫,不要每年存入等 額的現金,而是在40歲生日時直接存入一大筆可以滿足她退休計畫的錢。請問 大樂透獎金至少要多少錢才夠呢 ? 如果大樂透獎金為$1,500,000 , 請問足以支 應退休計畫嗎?若是可以,請問小陳退休後每年可提領的金額增加多少? 若是不 足以支應,請問小陳每年要再存入多少錢才能支應她的退休需求? ( 假設不考慮 稅賦等影響因素 ) (3) 假設小陳的公司提出員工分紅計畫 ,每年會有$12,500 元分紅直接存在她的儲蔡 帳戶。此外,小陳預期在她 55 歲生日時,可從一筆家族信託基金領到$120,000, 到時她也會把這筆基金直接存到她的退休金帳戶。請問,若有分紅計畫和家族 信託基金的幫助,小陳每年應該還要存入多少錢,來支應她的退休計畫呢?
