Answer:
Explanation:
Monthly payments from <em>mortgages</em> are calculated with the compounding montly interest rate.
Thus, you can "calculate" the monthly rate and the multiply by 12 to obtain the <em>APR</em> (annual percentage rate).
The equation for the <em>monthly payment </em>is:
![Monthly\text{ }Payment=Loan\times \bigg[\dfrac{r(1+r)^t}{(1+r)^t-1}\bigg]](https://tex.z-dn.net/?f=Monthly%5Ctext%7B%20%7DPayment%3DLoan%5Ctimes%20%5Cbigg%5B%5Cdfrac%7Br%281%2Br%29%5Et%7D%7B%281%2Br%29%5Et-1%7D%5Cbigg%5D)
- Loan = 80% × $1,800,00 = $1,440,000
- Monthly payment = $10,800
- t = number of months = 25 × 12 = 300
Substitute:
![\$10,800=\$1,440,000\times \bigg[\dfrac{r(1+r)^{300}}{(1+r)^{300}-1}\bigg]](https://tex.z-dn.net/?f=%5C%2410%2C800%3D%5C%241%2C440%2C000%5Ctimes%20%5Cbigg%5B%5Cdfrac%7Br%281%2Br%29%5E%7B300%7D%7D%7B%281%2Br%29%5E%7B300%7D-1%7D%5Cbigg%5D)
You must find r but it is very difficult to make it the subject of the equation; thus, the best is to do succesive calculations:
Tests:
r monthyly payment
- 0.01 $15,166.43 > $10,800 ⇒ lower
- 0.005 $ 9,277.94 < $10,800 ⇒ increase
- 0.006 $10,362.08 pretty close; increase a little bit
- 0.00639059 $10,800 ↔ this is the number
Multiply the rate by 12 (to obtain the APR): 0.00639059 × 12 = 0.07668708 = 7.67%.

Supply-side economics attempts to stimulate output and lower unemployment by reducing taxes to stimulate investment and consumer spending.
<h3>What is supply-side economics?</h3>
Supply-side economics is a economics theory that focuses on the supply of labour and goods. It postulates that taxes and benefits can be used as incentives to stimulate the economy.
Supply-side economics was introduced by Arthur Laffer and implemented by Pres. Ronald Reagan in the 1980s.
The Answer is D cost and benefit ranked in progressive units.
