Answer
342, 000 dollars
Work Step by Step
We plug in the given value to find:
$y-210,000=12,000(x-7)$
$y-210,000=12,000(18-7)$
Now, we use PEMDAS, a method for simplification. This acronym reminds us that we must first address parentheses, and then exponents. Next, we address multiplication and division, going from left to right. Lastly, we simplify addition and subtraction from left to right. This gives:
342,000
