✔ 最佳答案
(300-6*45)/6=5

Mr Ho can buy at most 5 cans

因為佢要買6張movie tickets, 所以用$300減去6張movie tickets的錢,
最後除$6就是了.

呢題答案好靚,係整數,
如果係小數,eg. 3.4, 就只取整數, 小數點後的要捨去,
因為冇3.4罐汽水的:)

逐步逐步黎啦~

6*45=270 (*係乘咁解)

300-270=30

30/6=5

The price of the ticket: $45*6 = $270

Money left : $300- $270 =$30

咁條式可以咁寫: ($300-45*6)/6 =5

嘻嘻~
正如我頭先同你講~
你發問的標題最好是「數學題」、「代數應用」會好一點~
清楚一些~

你應該是學解方程。

Let x be the number of cans of soft drink that he can buy at most.

6*45 + 6x = 300
6x = 30
x = 5
