✔ 最佳答案

1. Let x gram be the additional oat of each box.
4(220+x) = 1000
220+x=250
x=30

2. not enough data is given
only can be said to be this:
Let $x and $y be the 普通位船票 and 豪華位船票 respectively.
24x +360=24y
x+15=y

3.Let x L be the capacity of the oil tank.
5x/6 -3 =18
5x/6 = 21
5x = 126
x=25.2

1.設每盒加送了x克
(220+x)x4=1000克 (1公斤=1000克)
880+4x=1000
4x=120
x=30g
