各位大大好，今天做Q時遇到一題覺得很難了解語意，題目如下: Three friends are buying a gift for a friend. Declan contributes 4 dollars more than 1/4 the cost of the gift, Ed contributes 1 dollar less than 1/3 the cost of the gift, and Frank contributes the remaining 22 dollars. What is the cost of the gift? 官方解法是: Let x = gift cost Equation = (4+1/4x)+(1/3x-1)+22=x So x = 60 然而我的問題是 "4 dollars more than 1/4 the cost of the gift" 怎麼變成 4+1/4x ? 一直無法了解語意 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 111.83.48.169 ※ 文章網址: https://www.ptt.cc/bbs/GRE/M.1445827985.A.B41.html
