- Three 1-gallon cans of paint at $13.22 each: 3 x $13.22 = $39.66 
- Two paint brushes at $12.22 each: 2 x $12.22 = $24.44 
- $145 for a helper

Total estimated cost = $39.66 + $24.44 + $145 = $208.1

When rounding to the appropriate significant figures (which is determined by the least precise measurement, in this case $145), the answer becomes $209.
