2y-4=3y-5
-4=y-5
1=y
Answer: y=1
For 8, 15.25*18=274.5, 274.5/2= 137.25 or 137 1/4
for 9, 11*13=143, 143/2= 71.5 or 71 1/2
Answer:
2.9 is the correct information
Answer:

Step-by-step explanation:
Given
--- time (years)
--- amount
--- rate of interest
Required
The last 10 payments (x)
First, calculate the end of year 1 payment


Amount at end of year 1




Rewrite as:
Next, calculate the end of year 1 payment


Amount at end of year 2



Rewrite as:

We have been able to create a pattern:


So, the payment till the end of the 10th year is:


To calculate X (the last 10 payments), we make use of the following geometric series:




The amount to be paid is:
--- i.e. amount at the end of the 10th year * rate of 10 years

So, we have:





The geometric sum can be rewritten using the following formula:


In this case:



So, we have:




So, the equation becomes:

Solve for x


Approximate
