An investor invested a total of $1,100 in two mutal funds. one fund earned a 7% profit while the other earned a 3% profit. if the investor's total profit was $45, how much was invested in each mutal fund?

I believe a total of $527.5 was invested in each mutual fund.

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
