D is the correct answer partly because it's the only equation that has the correct outcome and partly because you have to divide 1313 by 4 anyways for the answer to make sense.
number of cups you have ÷ number of cups per serving = number of servings

Same as last time:
d^2=(x2-x1)^2+(y2-y1)^2
d^2=(6--1)^2+(-2-4)^2
d^2=7^2+(-6)^2
d^2=49+36
d^2=85
d=√85 (85=5*7 and both 5 and 7 are prime so √85 cannot be simplified any further)
The exact distance is √85 units.
