Hobbs Mules charges $80 for a 2-hour mule ride and $144 for a 4-hour mule ride. The table down below shows how much McGee Mules
Nataliya [291]

Answer: If a group wants to take a 3 hour ride they should choose Hobbs Mules.

Step-by-step explanation:

First figure out how much a 3 hour ride at McGee Mules would cost. Do this by setting up a proportion, then solving it.

Numerator = Time       Denominator = Cost

\frac{1}{42} = \frac{3}{x}  42 x 3 = 126/1 = 126  So a 3 hour ride with Mcgee should cost $126.

Next figure out how much a 3 hour ride at Hobbs Mules would cost by doing the same thing.

\frac{2}{80} = \frac{3}{x}   80 x 3 = 240/2 = 120  So a 3 hour ride with Hobbs should cost $120.

In conclusion, The group should choose Hobbs because they price is $6 cheaper.

Answer:

w=80

Step-by-step explanation:

The Exterior Angle Theorem states: The exterior angle formed by an extended sign of the triangle is the sum of the two angles in the triangle that it is not directly next to.

In this case, the exterior angle is w+44.

The interior angles we can use are w and w-36.

We can set up an equation:

w+44=w+w-36

Combine like terms.

w+44=2w-36

Add 36 to both sides.

w+80=2w

Subtract w from both sides.

w=80
