✔ 最佳答案
(300-6*45)/6=5Mr 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
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
