Answer:
I believe that the correct answer would be A) 170t = 4050 - 100t
Explanation:
With "t" meaning time we can put it next to 170 and with 100.
However, because 170t is filling up, we don't add a negative sign in the front; this is the opposite for 100t since it drains instead of filling.
Equation: 170t, -100t
Now since 170t is a different expression from the other two terms we will have to put an equal sign to separate the two.
Equation: 170t = -100t
For the Second part of the equation, we first add 4050 since it's the starting amount and NOT the change in amount.
Equation: 170t = 4050, -100t
We then put -100t at the end of 4050 since it's draining from 4050.
Equation: 170t = 4050 - 100t
I hope that this was helpful!
