Question

A bucket is filled with water up to the 4 gallon mark. The bucket springs a leak and water begins draining at a constant rate of 5/19 gallons per minute. Write a formula to determine the number of gallons of water n in the bucket in terms of the number of minutes t the water has been draining

Answer 1

n = 4 -
`(5)/(19)`t

Explanation:

n determines the amount of water in the bucket, it's basically the total, so that's why it's there. 4 is the number of gallons of water that you started with and 5/19 is the number of gallons that are draining per minute. t is the amount of time or minutes that have gone by. So, that's why the equation is n = 4 -
`(5)/(19)`t
