A researcher collects data on the growth of a vine and finds the expression 2.25 + 0.25d can be used to determine the length of the vine, in feet, for any day, d, after she started her observation. What does 0.25d represent in this expression?

• 0.25d represents the amount of feet the vine has grown d days after the researcher started observing it.

• 0.25d represents the amount of feet the vine grows in a single day

• 0.25d represents the length of the vine on the day the researcher started her observations.

• 0.25d represents the number of days after the researcher started observing the vine.

Joan has a gym gift card worth $100. Each time she visits the gym, $12 is deducted from the amount remaining on the gift card. Which equation can be used to determine the total amount of money (t), in dollars, remaining on the gift card after Joan visits the gym d times?

• t = 12 - 100d

• t = 100d - 12

• t = 12d - 100

• t = 100 - 12d
