想将题目给你翻译一下:
Barb 的摩托车的油箱可以装2加仑汽油,并且1加仑汽油可以使车行驶m米.如果每加仑汽油要花费1.25美元,Barb 花了d美元来加他的油箱加满,下面那一个选项代表她加满油之前油箱中的汽油的总量.
Barb花了d美元 加油,那么新加的油有d/1.25加仑了,而油箱加满时有2加仑,所以没加油之前,摩托车的油箱中的油=2-(d/1.25).所以选C.
Barb的摩托车邮箱可以装2加仑汽油,1加仑汽油可以行驶m英里。如果现在汽油的单价是¥1.25美元/加仑,Barb花了d美元加满油箱。下面的哪个公式可以表示Barb摩托车油箱加油前的油量?
答案当然是C啦
加油前=2(加油后满油箱)-d/1.25(d美元油的体积)...
