Steven used 3 cups of whole wheat flour and x cups of sugar in the recipe. What is the equation that can be used to find the value of y, the total amount of dry ingredients that Steven used in the recipe, and what are the constraints on the values of x and y? a) y=x+3; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 3.
b) y=3x; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 3.
c) y=3x; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 3.
d) y=x+3; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 3.
