He Fritzes are buying a house that sells for ​$176 comma 000 .
The bank is requiring a minimum down payment of 15
​%.
To obtain a 20
​-year
mortgage at 11.0
​%
​interest, they must pay 3

points at the time of closing.
​a) Determine the required down payment.
​b) Determine the amount of the mortgage on the property with the 15
​%
down payment.
​c) Find the cost of 3

points on the mortgage.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
