Answer:

At start of 2017 house worth = $231,525

Step-by-step explanation:

To find the new value worth of the house in each year, you add the increase in worth of house in the preceding year and the worth of the house in the preceding year. How do I learn

At start of 2014 house worth = $200,000

At start of 2015 house worth = 2014 house worth + 5% of 2014 house worth

At start of 2015 house worth = $200,000 + 5% of 200,000

= 200,000 + 5/100 * 200,000

= 200,000 + 10,000 = $210,000

At start of 2015 house worth = $210,000

At start of 2016 house worth = 2015 house worth + 5% of 2015 house worth

At start of 2016 house worth = $210,000 + 5% of 210,000

= 210,000 + 5/100 * 210,000

= 210,000 + 10,500 = $220,500

At start of 2016 house worth = $220,500

At start of 2017 house worth = 2016 house worth + 5% of 2016 house worth

At start of 2017 house worth = $220,500 + 5% of 220,500

= 220,500 + 5/100 * 220,500

= 220,500 + 11,250 = $231,525

At start of 2017 house worth = $231,525

X| 25 | 35 | 45 | 55 |
Yanka [14]
A graphing calculator can do a linear regression on these points very easily. The y-intercept is 107.

_____
If you want to do this by hand, you can use the 2-point form of the equation for a line, then evaluate for x=0.
.. y = (100 -102)/(35 -25)*(x -25) +102
.. y =-2/10*(0 -25) +102
.. y = 107

It will take 20 months for the cost to be same.

Step-by-step explanation:

Apartment A;

Security deposit = $1000

Each month cost = $1200

Let,

x be the number of months.

A(x) = 1000 + 1200x

Apartment B;

Security deposit = $1500

Each month cost = $1175

B(x) = 1500 + 1175x

The cost will be same when the functions are equal, therefore,

A(x) = B(x)

1000+1200x=1500+1175x\\1200x-1175x=1500-1000\\25x=500

Dividing both sides by 25

\frac{25x}{25}=\frac{500}{25}\\x=20

It will take 20 months for the cost to be same.
