Answer:
<em></em>
<em></em>
<em></em>
Step-by-step explanation:
Given
The attached graph
Required
Determine the solution
The solution here is the intersection points of the two lines. From the attachment, both lines meet


<em>Hence, the solution is: </em>
<em></em>
100$×0.05= 5 $ is her annual interest
qusetion number 1 . 5$× 6 years = 30 $
for question number 2 . 100$+30$=130$
Your answer is the 3rd option.

You must divide by π on both sides, therefore d=c/π
