[SOS!!]一個英文數學問題(急) [複製鏈接]

資料:Taxi Fare Table
First 2 km $18
Every 0.2km or part thereof $1.5
Every Baggage $5


問題:A and B are 4km apart.B and C are 13.2 km apart.Paco took a taxi form A to C by going through B.How much taxi fare should he pay?

要求列式,答案

A and C are 13.2+4 km = 17.2
first two km = $18
so there are 15.2 km left
15.2 / 0.2 = 76
76*$1.5 =  $114

$18+$114 = $132


If paco has one baggage,plx add $5 more

上面解釋
條式:
$18+[(17.2-2)/0.2]*$1.5
=18+(15.2/0.2)*1.5
=$18+76*1.5
=$18+$114
=$132

如果有行李就1件+5蚊

你解答唔到就咪回啦

回黎托咩- -?

中文:
頭2公里=18$
每0.2公里=1.5$
每一件行李=5$

問題:A至B係4公里.B至C係13.2公里.paco由a去c,穿過b.
佢要比?$

無野:D

  18+(4+13.2-2)/ 0.2x 1.5
=18+15.2/ 0.2x 1.5
=18+76x 1.5
=18+114
=$132

the distance between A and C through B=17.2km
The taxi fare required=15.2/0.2   *1.5 +18 =$132

太難了
