### Problem 20

A house purchased for $250,000 in 2010 increases in value by $10,500 each year.

#### a. Express the value of the house as a linear function of \( t \), the number of years after its purchase.

To express the value of the house as a linear function of \( t \), we can use the formula for a linear function: 

\[ V(t) = mt + b \]

where:
- \( V(t) \) is the value of the house at time \( t \),
- \( m \) is the rate of increase in value per year,
- \( t \) is the number of years after the house was purchased,
- \( b \) is the initial value of the house.

Given:
- Initial value \( b = 250,000 \),
- Annual increase \( m = 10,500 \).

So, the linear function is:

\[ V(t) = 10,500t + 250,000 \]

#### b. According to your function, when will the price of the house reach $334,000?

To find out when the price will reach $334,000, we need to solve for \( t \) in the equation:

\[ V(t) = 334,000 \]

Using the linear function from part (a):

\[ 334,000 = 10,500t + 250,000 \]

Subtract 250,000 from both sides:

\[ 334,000 - 250,000 = 10,500t \]

\[ 84,000 = 10,500t \]

Now, solve for \( t \):

\[ t = \frac{84,000}{10,500} \]

\[ t = 8 \]

So, the price of the house will reach $334,000 in 8 years after its purchase, which will be in 2018.
