You would add 3 1/7 to 5 6/7
Answer:
5.6%
Step-by-step explanation:
The computation of the annual percentage yield is shown below:
Given that
Initial investment amount is 2,500
And, there is an annual rate of interest i.e. 5.6%
Since we have to determine the annual percentage yield i.e. equivalent to the annual rate of interest i.e. 5.6%
Hence, the above represent the answer
Let 
be the cost, respectively, of a notebook and a pen. If you buy 2 notebooks and 3 pens (which we know is a cost of $14.50), you spend 
Similarly, if you buy 1 notebook and 2 pens (which we know is a cost of $7.50), you spend 
These two equations form the following system:
Multiply the second equation by 2:
Subtract the first equation from the second:
So, a pen costs 0.5 dollars. Plug this equation in the second equation:
