Answer:
The Annual rate of interest for the mortgage is 1.8%
Step-by-step explanation:
Given as :
The mortgage principal = p = $167,000
The time period of mortgage = t = 20 years
The Amount paid towards mortgage in 20 years = A = $240,141
Let the Annual percentage rate on interest = r % compounded annually
Now, <u>From Compound Interest method</u>
Amount = Principal × 
Or, A = p × 
Or, $240,141 = $167,000 × 
or,
= 
Or , 1.437 = 
Or,
= 
or, 1.018 = 
Or,
= 1.018 - 1
Or,
= 0.018
∴ r = 0.018 × 100
i.e r = 1.8
So, The rate of interest applied = r = 1.8 %
Hence, The Annual rate of interest for the mortgage is 1.8% Answer
<span>(x - y + 1) - (x + y - 1)
x - y + 1 - x - y + 1
= (x - x) + (y - y) + (1 + 1)
= -2y + 2
In short, Your Answer would be: -2y + 2
Hope this helps!</span>
The answer would be the first person said 6, -26,102
