Let x be Milo's annual salary before his raise. Then, we can set up the equation:
x + 0.1x = 33000
Simplifying the left side, we get:
1.1x = 33000
Dividing both sides by 1.1, we get:
x = 30000
Therefore, Milo's annual salary before his raise was $30,000. The correct answer is choice C. Let x be Milo's annual salary before his raise.
His new salary is 10% more than his old salary, so:
x + 0.10x = 33,000
Simplify and solve for x:
1.10x = 33,000
x = 30,000
Therefore, Milo's annual salary before his raise was $30,000.
