發問:
Mr Ho has $300 and he wants to buy 6 movie tickets and some cans of soft drink. If the prices of a movie ticket and a can of soft drink are $45 and $6 respectively,how many cans of soft drink can Mr Ho buy at most?
最佳解答:
(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. 2013-09-22 19:15:23 補充： 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:) 2013-09-22 19:18:24 補充： 逐步逐步黎啦~ 6*45=270 (*係乘咁解) 300-270=30 30/6=5
其他解答:
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 2013-09-22 19:13:14 補充： 咩唔得? 皎潔明月 是答對了的!!! ^_^|||||唔得bo~~~~~~~~ 2013-09-22 19:18:33 補充： 我唔系e個意思 OKOK~
