Answer:
Option A.
Step-by-step explanation:
Note: Let as consider, we have to find the total amount after 9 years.
It is given that,
Principal amount = $1000
Rate of compound (yearly) interest = 15% = 0.15
Time = 9 year
The formula for total amount is
where, P is principal, i is rate of interest and n is number of years.
Substituting P=1000, i=0.15 and n=9, we get
So, the total amount after 9 years is $3517.88.
Therefore, the correct option is A.

Answer:
The fraction of the students who failed to went partying = ![\frac{1}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%7D)
Step-by-step explanation:
Let total number of students = 100
No. of students partied are twice the no. of students who not partied.
⇒ No. of students partied = 2 × the no. of students who are not partied
No. of students partied before the exam = 20 % of total students
⇒ No. of students partied before the exam =
× 100
⇒ No. of students partied before the exam = 20
No. of students who not partied before the exam = ![\frac{20}{2} = 10](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B2%7D%20%3D%2010)
Thus the fraction of the students who failed to went partying = ![\frac{10}{100} = \frac{1}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B100%7D%20%3D%20%5Cfrac%7B1%7D%7B10%7D)
Answer:
434
Step-by-step explanation:
310 times .4 (percentage) = 124 which is how much she gained, then you add that onto the original amount to find how many she has now, which is 434
