    hint: our expression will look something like this: (number of 14 oz cans)*14+ (number of 70 oz bottles)*70 number of 14 oz cans = x total number of cans + bottles = 940 keep going from here

    (hint: your answer won't be a number, it'll be an expression using the variable x)

    number of cans = x number of cans + bottles = 940 number of bottles = 940 - x does that make sense so far?
