<u>Step-by-step explanation:</u>
Here we have , Hoover Dam spans the Colorado  River on the Nevada-Arizona state  line. For its construction, the federal  government purchased 21,670,000  pounds of gates and valves. We need to find BEST estimate of this  amount . Let's find out:
21,670,000  pounds 
⇒ 21,670,000  pounds 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Now, Rounding of 2.167 we get 2  ,So
⇒ 
Hence ,  BEST estimate of this  amount is  . Correct option A. 2 x 10^7 .
 . Correct option A. 2 x 10^7 .
