Yuling posted this question to me...
20 fish burger and 50 chicken rice cost $230
10 fish burger and 25 bottle of water cost $65
How much is a bottle of water cost?
Answer: burger $4, Chicken rice $3, bottled water $1
But how to get these answer? Workings?
When I saw...I thought the question was given wrongly.
Haha..cos..1st glance, I knew I could not solve it via the simultaneous equation way..
Fish burger = f
chicken rice =r
bottle of water =b
20f + 50 c =230
10f +25 b = 65
2f + 5c = 23
2f + 5b = 13
How???how to solve??or just pluck any number in?try and error?
