The asymptotes are Y=2 and X=2, -2
Let x be the total number of beavers. We mark 119 out of x beavers. Then, we found 39 marked beaver out of 89 caught beavers. So, if we build the proportion

we get, solving for x,

So, it is reasonable to suppose that there are about 272 beavers in total. Note that this is an estimate, both numerically and conceptually, since we have no information about the set of beavers caught at the beginning and the end of our experiment.
Answer: $0.1428/mi or about 14 cents per mile
Steps:
While the cost of car = $5,000.00 is not an operating cost, the annual decrease of value is. So, given that the market value after 1 year = $3,800, the value loss is 5000-3800=$1200 for the year.
Add cost of gas and oil = $750.00, Repairs/Maintenance = $250.00, Insurance = $300.00, to get $2500 total operating cost.
The cost per mile is $2500/17500 miles = $0.1428/mi or about 14 cents per mile
