A rental company rents a luxury car at a daily rate of $37.51 plus $.25 per mile. Paul is allotted $120 for car rental each day. Write an equation to represent the cost C of renting a car and driving x miles. How many miles can Paul travel on the $120?

385 miles

Step-by-step explanation:

$120 - $43.01 = $76.99

$76.99 = 7699 cents

7699/20 = 384.95 miles

So, the business man can travel

385 miles on the $120.

Hope this helps.

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.
