Question 8

Explanation

This problem can be solved using the concept of a Linear Function or an Arithmetic Sequence, because the land price increase is constant (fixed) every year.

The initial land price ($a$) is given as $10,000,000$ and the annual price increase ($b$) is $1,200,000$. We want to find the land price after $5$ years.

If we model this as a linear function where $y$ is the land price and $x$ is the number of years, the equation is:

Substitute $x = 5$ to calculate the land price after $5$ years:

Thus, the land price in $5$ years will be $Rp16.000.000,00$ per square meter.
