Answer:
B. $2862
Step-by-step explanation:
Using n=5 in the given equation, we get ...
A(5) = 2700 + (5-1)(.015·2700) = 2700 +4(40.50)
A(5) = 2862.00
In year 5, you will have $2862 in the account.

<em>Comment on the given equation</em>
The given equation tells you the amount in the account at the <em>beginning</em> of the year, before it earns any interest. Since that is the equation given, we presume that is the answer desired. In most "account balance" problems, you are interested in the amount at the <em>end</em> of the interest-earning period.
Answer:
% of increase = 2.5%
Explanation:
The percentage of increase can be calculated using the following rule:
% of increase = (amount of increase / original amount) * 100
where:
amount of increase = new price - old price = 2.89 - 2.82 = $0.07
original amount = $2.82
Substitute in the equation to get the percentage of increase as follows:
% of increase = (0.07 / 2.82) * 100 = 2.4822 % which is approximately 2.5% to the nearest tenth
Hope this helps :)
