Question

Mary used the equation x = $4 * y to represent the table above. What mistake did she make, and what should the correct equation be to represent this table?

Answer 1

Answer:  she has to remove the $ sign from the equation

Step-by-step explanation:

Answer 2

Mary removed the dollar sign from (X.)
We know this because $4.00x$5.00=$20.00 so that’s correct and we know that $12.50x $4.00=$50.00. So, our only error here is that there is no dollar sign in our (X) numbers. So that is Mary’s mistake. We can correct it by simply adding a dollar sign to 20 to make $20.00 and adding another dollar sign to 50 to make $50.00

Hope this helps!
