A NEW OG 2021 QUESTION
Its a Conversion Question
Milk production in 2014 = 2.7 billion pounds
= 2.7 x 1000 = 2700 million pounds
Milk production in 2007 = 980 million pounds
Increase in milk production = 2700 -980
= 1720 million pounds
1 gallon = 8.6 pounds
=> 1 pound = 1/8.6 gallons
Thus 1720 million pounds = 1720 x 1/8.6 gallons
Round 8.6 to 10 (given the large difference in options)and you would have 172 million gallons (approx.)
Nearest value to this is 200 million pounds (OPTION B)
