How many dots are there at t minutes? Solve the problems by your preferred method. Your solution should indicate how many dots will be in the pattern at 3 minutes, 100 minutes,
and t minutes. Be sure to show how your solution relates to the picture and how you
arrived at your solution.

The image to the question is missing, but I found a matching image, which is attached to this solution

3 minutes = 13 dots

100 minutes = 401 dots

t minutes = 4(t) + 1 dots

Step-by-step explanation:

From the image, the following can be noticed:

time (Mins)       dots

0                          1

1                           5

2                          9

The pattern gotten from this progression is that, if the time is multiplied by 4, and the result added to one, the result will be the number of dots.

hence, when the time is 0 minutes:

0 × 4 = 0

0 + 1 = 1 ( 1 dot)

when the time is 1 minute

1 × 4 = 4

4 + 1 = 5 (5 dots)

when the time is 2 minutes

2 × 4 = 8

8 + 1 = 9 ( 9 dots)

Therefore,

when the time = 3 minutes

3 × 4 = 12

12 + 1 = 13 dots

at 100 minutes:

100 × 4 = 400

400 + 1 = 401 dots

at t miutes

t × 4 = 4t

4t + 1 = number of dots

Therefore number of dots at t minutes = 4(t) + 1
