A 50 cm length of ribbon costs x dollars. Find an expression for the cost of y meters of ribbon. Give your answer to its simplest form.

Let y = the total cost for a certain amount of x ribbons
Let x = the cost per ribbon
We write a linear equation to express a relation between x, y and 50.
We say our equation is y = 50x.
Does this make sense?
Make sure to convert from cm to meters.
