A machine can fill 5400 bottles in three hours. How many dollars can it fill in eight hours?

To calculate the bottles filled in 8 hours, we will use the equation:

Bottles filled = Bottles filled per hour * Number of hours

Bottles filled in 8 hours = 5400 bottles/hour * 8 hours = <<5400*8=43200>>43200 bottles.

Since the machine can fill one bottle per dollar, the machine can fill 43200 dollars in 8 hours. Answer: \boxed{43200}.

To solve this problem, we need to find the number of bottles the machine can fill in eight hours, and then calculate the dollar amount based on that.

First, let's find the machine's filling rate per hour. We can do this by dividing the total number of bottles filled (5400) by the total number of hours (3):
Filling rate per hour = 5400 bottles / 3 hours = 1800 bottles/hour

Next, let's calculate the number of bottles the machine can fill in eight hours. We can do this by multiplying the filling rate per hour by the number of hours:
Number of bottles filled in 8 hours = 1800 bottles/hour * 8 hours = 14400 bottles

Finally, to calculate the dollar amount, we need to know the dollar value per bottle. If you provide the dollar value per bottle, I can calculate the total dollar amount.

To find out the number of dollars the machine can fill in eight hours, we need to first determine the number of bottles the machine can fill in one hour, and then multiply it by the number of hours.

Given that the machine can fill 5400 bottles in three hours, we can find the number of bottles it can fill in one hour by dividing 5400 by 3:

Number of bottles filled in one hour = 5400 / 3 = 1800 bottles

Now, to find the number of dollars the machine can fill in eight hours, we need to multiply the number of bottles filled in one hour by eight:

Number of bottles filled in eight hours = 1800 * 8 = 14400 bottles

Therefore, the machine can fill 14,400 bottles in eight hours. However, the question asks for the number of dollars the machine can fill, so we need to determine the dollar value of each bottle. If the dollar value of each filled bottle is provided, we can multiply it by the number of bottles to find the total dollars.
