Answer

231 million

Work Step by Step

We start with the given equation: $y = .096x+72.81$ We want to find when y is equal to 95, so we plug in 95: $95 = .096x+72.81$ 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: $x = 231$.
