$15 * 3 days = $45
$57 - $45 = $12
$12 / $0.75 = 16
He interviews 16 people to earn a total of $57.
He would have earned 17.75
Just subtract 6.75 from 24.50
24.50-6.75=17.75
It's similar to hedging, or not putting all of your eggs in one basket. Let's say you only invest in oil. You're return on investment is at the mercy of oil's standing in the commodities market, meaning, if the price of oil drops, so to does your ROI. However, if you hedge oil with something like, say solar power, your are now "protected" from fluctuations in either market.

<h3>Answer: Choice B</h3>
![12b^2\sqrt[3]{2a}](https://tex.z-dn.net/?f=12b%5E2%5Csqrt%5B3%5D%7B2a%7D)
In word form, this is 12 b squared (RootIndex 3 StartRoot 2 a EndRoot
Or you could say 12b^2 times the cube root of 2a

The idea here is that we break the cube roots into smaller pieces, so we pull out perfect cubes when factoring.
