Given:
Principal amount = $2000
Rate of interest = 3.5% compounded quarterly.
Time = 6 years
To find:
The amount after 6 years.
Solution:
The formula for amount after compound interest is:
Where, P is principal, r is rate of interest in decimal, n is the number of time interest compounded in an year and t is the number of years.
The interest is compounded quarterly, so 
.
Substituting 
, we get
Approximate the value to the nearest hundredth.
The amount after 6 years us $2465.10. Therefore, the correct option is A.
(11+30-5) - (1-5)
(41-5) - (1-5)
(36) - (-4)
answer: 32
Solution
- 89 gallons contains 40 gallons twice such that:
- This means that we can find at least 200% of 40 gallons in 89 gallons. This gives us what to expect.
- To get the percentage we are looking for, we should use the formula:
New, in this case, is 89 gallons, Old is 40 gallons.
- Thus, we can calculate the percentage as follows:
Thus, the answer is 222.5%
The answer is the first one, because the number of tires properly installed on Monday will not be the same as everyday.
