Mia and mai want to to rent a canoe at the boat house on the river. it cost $6.95 to rent a canoe for 1 hour. the price per hour stays the same for up to 3 hours of rental. after 3 hours, the cost decreases to $4.50 per hour. how much would it cost mia and mai to rent a canoe for 4 hours

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

so, converting firstly the mixed fractions to improper fractions and then "adding".
