Clayton volunteered for 33 hours over a 6-week period at the local community center. assuming he continues to volunteer at the same rate, how many volunteer hours will clayton accumulate in a 20-week period?

For this case, we can make the following rule of three:
 6 week > 33 hours
 20 week > x
 From here, we clear the value of x.
 We have then:
 x = (20/6) * (33)
 x = 110 hours
 
 Clayton will accumulate 110 volunteer hours in a 20-week period
