Question

Quizplus · Accepted Answer

The total cost can be calculated as follows:
3 cans of paint x $13.22/can = $39.66
2 paint brushes x $9.53/brush = $19.06
Helper = $135
Total estimated cost = $39.66 + $19.06 + $135 = $193.72
Since we are asked for the appropriate significant figures, the answer should be rounded to the nearest dollar, which is $194 (since the tens digit is greater than 5). Therefore, the correct choice is C.
