C. 2.84%

Step-by-step explanation:

We are trying to figure out how much money will be made from the interest each year in percentage form so to set up the problem we need to first find the earnings from this year: 2,056.72 - 2,000 = 56.72

Then we will put 2,000 below that because that was the original full account deposit used to make the interest.  100 automatically goes on the other side because it is the full value of the percentage. Then solve the equation.

56.72       X

=

2,000     100

To solve for X start by multiplying the diagonal numbers, in this case 56.72 and 100. Then divide by the remaining number, 2,000.

I hope this helps a little :)

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:
