第一题 dimes是10美分硬币,quarters是25美分硬币,他一共有2.05美元(也就是20.5美分),他的10美分硬币比25美分少四个,问你他10美分硬币一共有多少钱
设他有X个25美分硬币,(X-4)个20美分硬币
25X+10(X-4)=20.5
X=7,X-4=3
所以他有三个10美分(30 cents in dimes)
第二题Mr.Jones以80000元卖了两套房子,一套赚了20%,一套亏了20%,问赚的减亏的剩多少钱?
赚的那套原价为 80000/(1+20%)=66666
赔的那套原价为 80000/(1-20%)=100000
所以总损益为(80000-66666)-(100000-80000)=-6666
亏损6666元
