A fish tank contains 600 gallons of water when full. The tank contains a permanent hole, which causes the tank to leak at a
constant rate of 12 gallons each week. Let w be the number of
weeks. Which of the following expressions describe the number of
gallons left in the tank after any given number of weeks.

a. 600 + 12w
b. 600 - 12w
c. 12 -600w
d. 12 + 600w

600 - 12w

Step-by-step explanation:

From the question, we are informed that a fish tank contains 600 gallons of water when full and that the tank

contains a permanent hole, which causes the tank to leak at a constant rate of 12 gallons each week.

If the number of weeks is represented by w, then the expression that describe the number of gallons left in the tank after any given number of weeks will be:

= 600 - 12w

For example let's say the number of weeks is 5 weeks. Using the expression,

600 - 12w

= 600 - 12(5)

= 600 - 60

= 540 gallons

There'll be 540 gallons after 5 weeks.

i think the answer is b.
