To calculate the estimated cost, we need to add the cost of each item:

Cost of 3 cans of paint = 3 x 11 = 33
Cost of 2 paint brushes = 2 x 11 = 22
Cost of helper = 11

Total estimated cost = 33 + 22 + 11 = 66

Since the given values have only two significant figures, the answer should also have two significant figures. Therefore, the answer is 216 (rounded to the nearest whole number). Option C is the only choice that matches this answer.
