A car rental company offers the following two plans for renting a car: Plan A: 30 dollars per day and 11 cents per mile
Plan B: 50 dollars per day with free unlimited mileage

Q: How many miles must one drive in order to justify choosing Plan B?

181.818181...Miles

Step-by-step explanation:

50 = 30 + 11X

X = 181.81818181...

If you multiply 11 by 181.81 repeting you will get 20 and 30 + 20 = 50

So You would have to go 181.81 repeating miles for it to be equal

If you are rounding up it would be 182 miles to justify choosing plan B

x intercept = (-1,0)   (4,0)

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
