Useful property: x% of y = y% of x
Here's why:
x% of y \(= (\frac{x}{100})(y) = \frac{xy}{100}\)
y% of x \(= (\frac{y}{100})(x) = \frac{xy}{100}\)
Answer: C
Not convinced?
40% of 340 \(= (\frac{40}{100})(340) = \frac{(40)(340)}{100}\)
340% of 40 \(= (\frac{340}{100})(40) = \frac{(340)(40)}{100}\)
Answer: C
