What is 4 hours 45 mins after 4:25 a.m.?
Add 4 hrs first:
4:25 + 4 hrs = ?
5:25, 6:25, 7:25, 8:25
4:25 a.m + 4 hrs = 8:25
8:25 a.m + 45 mins = ?
8:25 + 45 = 9:00
8:25 a.m + 45 mins = 9:00 a.m
4 hrs and 45 mins after 4:25 a.m is 9:00 a.m.

Answers:
- A) The equation is d = 2t
- B) Independent variable = time; dependent variable = amount of cookies
=========================================================
Explanation:
The independent variable is always long the horizontal axis. Often this is x, but we are using t in this case.
The variable t represents the amount of time in minutes. For instance, t = 2 means 2 minutes have elapsed. At this time, 4 cookies have been eaten as shown by the point (2,4). As another example, the point (3,6) means that d = 6 cookies have been eaten at time t = 3 minutes.
The equation is d = 2t because the '2' represents the rate of change of "eating 2 cookies per minute". Whatever the time value (t) is, we double it to get the value of d, which is the number of cookies eaten.
