Question

The total number of gallons of water in the tank, T, after w weeks can be represented by the equation T = -15w + 275. Which of the following is the best interpretation of the number 275 in the equation?

Answer 1

Answer: D

Step-by-step explanation:

      This 275 is a constant variable, meaning that the variable (in this case, w of weeks) won't change it. This means there was already 275 gallons in the tank, and was not added during the first week.

      This means the 275 in the equation represents the amount of water, in gallons, in the tank currently.
