Answer:
Let x equal the amount of time required for the second press to complete the job on its own.
The second press then operates at a rate of 1/x of the job per hour.
The two presses work together at a rate of 1/2 of the job per hour.
And the first press operates at a rate of one-sixth of the job per hour.
As a result, our equation to solve is:
1/6+1/x=1/2 multiply each term by 6x x+6=3x subtract x from each side x-x+6=3x-x group like terms together
2x=6 multiply both sides by 2 x=3 the number of hours required for the second press to finish the job

1/6+1/3=1/2
1/6+2/6=1/2\s3/6=1/2
1/2=1/2\salso\s(1/6)*2=1/3\s(1/3)*2=2/3\s2/3+1/3=1 (Only one job)
1=1
I believe it’s 71 but I could be wrong it depends on the formula I need to use
What the question is asking is: Where are those curves shooting off to as you get closer and closer to zero? Think about where the left-hand side is gong, and think about where the right hand is going. Are those numbers very large in the positive direction (more positive) and very large in the negative direction (more negative), or are they small in the positive direction (less positive) and small in the negative (less negative)?
200 per month for 60 months......200 * 60 = 12,000
difference is : 12,000 - 10,000 = 2,000 <==
