Answer:
A) y=400x+60,000 (really no work needed)
B) 67,200 volumes
C) 50 months after March 2004
Step-by-step explanation:
B) you will find the # of months between march of 2004 and september 2005, which would be 18 months (you exclude march of 2004) and substitute that number in for x in the first equation.
C) Instead of substituting in for x, we will substitute in for Y, so the equation will look like
80,000=400x + 60,000
and you would simplify this by isolating x, meaning that your answer will be 50, so you could say 50 months after march or you could actually find out the date.
