Acompany is planning to manufacture mountain bikes. the fixed monthly cost will be $400,000 and it will cost $200 to produce each bicycle.

I'm guessing that this is supposed to be an equation for cost.
First we take the 400,000, and add it to the rest,
400,000 +, now we add a variable,
400,000 + x, since it costs 200 dollars to make a bike, we'll add it to the variable,
400,000 + 200x < there's your equation!

Well if you want a equation for this it would be 200x+400000= Let me know if there is something else that you wanted for this question.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
