James has 30 teeth. His dentist drills 4 of them and caps 7 more teeth than he drills. What percentage of James' teeth does the dentist fix?
A re re x ke dingwaga tsa ga Colin jaanong.
(x+7)*5=(x+25)*3
5*x+35=3*x+75
2*x=40
x=<<20=20>>20
#### 20 

First find the total number of teeth the dentist caps: 4 teeth + 7 teeth = <<4+7=11>>11 teeth
Then find the total number of teeth the dentist fixes: 11 teeth + 4 teeth = <<11+4=15>>15 teeth
Then divide that number by the total number of teeth and multiply by 100% to find the percentage of teeth he fixes: 15 teeth / 30 teeth * 100% = 50%
