Answer:
the answer of your question is B
180 -134 = 46 is PRQ
46 x 2 = 92 is POQ acute angle
360 - 92 = 268 is POQ reflex angle

First, combine like terms:

Now just simplify the coefficients of x and y. We do this by converting each pair of fractions to ones with a common denominator. Then we can combine them easily.


So the simplified expression would be

You're going to want to take the total, which is $353.00 and subtract the initial cost, which is $84.00, the number now should be $269. Using that total divide it by $68.00, there you should find your answer of about 4 hours. The precise answer is 3.99588235. But you would round that to 4 hours.
