The function g (d) = 600-50d represents the number of gallons of water in a tank d days after the tank is filled. What does the value 50 represent in this situation?

The tank had 50 gal of water in it before it was filled.

The tank had 50 gal of water in it after it was filled.

The volume of the tank decreases by 50 gal every day.

The volume of the tank increases by 50 gal every day.

Given that a function

g (d) = 600-50d

Here g is dependent variable and d independent variable

We have to interpret the term 50 in this situation.

g = 600-50d

600 represents the initial amount of water in the tank i. e. when d = 0

Let us assume d changes by 1 day. say d+1

then new g = g' = 600-50 (d+1) = 550-50d

i. e. whenever d increases by 1 unit, g decreases by 50 galons

Hence correct answer is

The volume of the tank decreases by 50 gal every day.

The volume of the tank decreases by 50 gal every day.
