C. 17 r 1 is the correct answer
8.9% is equal to 0.089 because a percent is over a 100. So, you can just multiply the ROI by the investment to get:
Your answer is:
$712.
24/.30 is how you would get your answer and 80
If 24 of the 60 were saved then the percent saved is
(24/60) x 100
Let's imagine for a second that all 60 was saved, then 100% of the money would be saved. Which makes sense, because
(60/60) x 100 = 100%
So the amount saved dived by the amount earned all times 100 is the percent saved.
In AAA (Angle-Angle-Angle), triangles do not have the same size and only have 3 pairs of congruent angles.
In SSS (Side-Side-Side), if the three sides of one triangle are equal to the three sides of another triangle, the triangles are congruent.
