Question 1121723: The amount of oil imported to Country A from Country B in millions of barrels per day can be approximated by the equation yequals0.061 x plus 1.23, where x is the number of years since 1975. Solve this equation for x. Use the new equation to determine in which year the approximate
number of oil barrels imported from Country B per day will be 3.06 million.
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! y=0.061x+1.23
3.06 is y
3.06=0.06x+1.23
1.83=0.06x
divide by 0.06 both sides
x=30.5 years which would be 2005.5, or mid-2006, depending upon how 1975 was exactly defined. I define it as ending just before 1976, so 30 years would be just before 2006, and 30.5 in mid-2006.
