Answer :
The amount of water in the bucket after 9 minutes is (a) 88 ounces
How to determine the amount of water in the bucket after 9 minutes.
From the question, we have the following parameters that can be used in our computation:
f(t)=115-3t
- where f(t) is in ounces
- t is in minutes
This means that
f(t) = 115 - 3t
Also from the question, we have:
The amount of water in the bucket after 9 minutes.
This means that
t = 9
Substitute the known values in the above equation f(t) = 115 - 3t, so, we have the following representation
f(9) = 115 - 3 * 9
Evaluate the products
f(9) = 115 - 27
Evaluate the difference
f(9) = 88
Hence, the amount of water is 88 ounces
