Sarah's goal was to save $90 from her paycheck last month. She was within $12 of that goal. What were the maximum and minimum

amounts that Sarah could have saved?

Given:

Sarah's goal was to save $90 from her paycheck last month.

She  was within $12 of that goal.

To find:

The maximum and minimum  amounts that Sarah could have saved.

Solution:

Her goal = $90

Difference between actual savings and goal of saving is 12.

Maximum amount = $90 + $12 = $102

Minimum amount = $90 - $12 = $78

Therefore, the maximum and minimum  amounts that Sarah could have saved are $102 and $78  respectively.

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
