Algebra 014 Which situation is best modeled by this diagram? S CLEAR CHECK The total cost, t, of a meal that includes the prices of a salad, r, and a bottle of water, s. Your sister's height, t, if her height is s inches less than your height, r. The total miles, t, you can travel in s hours at a speed of r miles per hour. The total cost, r, to buy s children's passes and t adult passes.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
