Let's assume the productivity of the first worker = x cookies
Therefore, we can write the following equations from the given information:
1x = 15 (one worker can produce 15 cookies)
2x = 35 (two workers can produce 35 cookies together)
3x = 65 (three workers can produce 65 cookies together)
Solving these equations, we get:
x = 15 (The productivity of one worker)
Therefore, the average productivity of the first three workers = (15 + 15 + 15) / 3 = 45/3 = 15
Hence, the average productivity of the first three workers is 15 cookies, which is option D.
