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.
