Answer: the percent of study group students from outside the state is 13%
Step-by-step explanation:
The total number of students in the young woman's study group that are from the town where the young woman's school is located is 7%
The total number of students in the young woman's study group that are from in-state (but not from the school's town) is 80%.
Since the rest are from outside the state, the percent of study group students from outside the state would be
100 - (80 + 7) = 100 - 87 = 13%

Answer: 1 hour 20 minutes
Step-by-step explanation:
Given : The old machine could shred a truckload of paper in 4 hours.
Rate of work done by old machine = 
The new machine could shred the same truckload in 2 hours.
Rate of work done by new machine = 
Let 't' be the time taken by both of them working together , then we have the following equation:-

Since 1 hour = 60 minutes
Then, 
Hence, it will take 1 hour 20 minutes to shred the same truckload of paper if Ron runs both shredders at the same time.
P=s+t+r subtract r from both sides
P-r=s+t subtract t from both sides
P-r-t=s
