The unit rate in this problem is one payment per month. Since Martha has made 86 payments, that means it has been 86 months. Because of that, we can simply multiply 3335*86 to get 286810.
So she so far has paid $286,810 for her house payment
In the expression given, the "n" is referring to a certain term, in this case, it would be the 16th term. So in order to find the 16th term, all you have to do is substitute n as 16 in the expression, so the answer is

. So the 16th term of the sequence is -29.
The correct answer is letter B!!
Answer:
Actual length of w is 0.075 units.
Step-by-step explanation:
Given the actual length of side t is 0.045 cm.
we have to use the scale drawing to find the actual side length of w.
As given the actual length of t is 0.045 cm.
Hence, we can find the scale factor using the lengths of t i.e actual length and after scale drawing by dividing.
Scale factor is 
Hence, we get the scale factor.
Now, 
⇒ 
⇒ Actual length of w is 
Option B is correct.
