I had a question like this on my unit test, but i'm not sure if the answer($4.32) is right because i'm just remembering exactly what the question was, which i did 6 hours ago.
"john buys a slushie form macs( its a Canadian convenience, kind of like the Canadian version of 7 eleven) with a mix of coke and sprite. the cost for coke is 0.02/ml and 0.05/ml for sprite. he got 150ml with a total amount of $4.32 in his pocket. how much coke and sprite did he put in his mix?"
can some one show how to solve something similar to this or even this (if its right) step by step, thank you.
