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

you dont missed any details from there ?

Answer 2

total flour = wheat flour + white flour

so to get y (total flour) you just have to add the whole wheat (6) and the white flour (x)

for constraints on y and x, keep in mind that x cannot be negative, and use that fact to find the constraint on y
