Question

Otto used 6 cups of whole wheat flour and x cups of white flour in the recipe. What is the equation that can be used to find the value of y the total amount of flour that Otto used in the recipe, and what are the constraints on the values of x and y

Answer 1

Answer:

Well, there are x amounts of white flower and 6 cups of wheat flower.

So the total flower is x + 6

Given that  is the total, the equation you would use is:

y=x+6

The constraints are as follows:

y can only be > 6

And if y=0, x would have to be -6 (which is impossible)
