Answer:
300 points
Step-by-step explanation:
160 + 20 = 180
180 would have been 60 percent
180/60 = 300
300 would have been needed to pass
Proven by:
300 * 60% = 180
180 - 20 = 160
slope line of q= -1/2

16/8 = H
2 = H
Done!
Answer:
Two more people.
Step-by-step explanation:
If 4 people can mow a lawn in 6 hours, then 4 people can mow 1/6 of a lawn in 1 hour.
If 4 people can mow 1/6 of a lawn in 1 hour, then 1 person can mow 1/24 of a lawn in 1 hour.
If 1 person can mow 1/24 of a lawn in 1 hour, then 6 people can mow 1/4 of a lawn in 1 hour.
If 6 people can mow 1/4 of a lawn in 1 hour, then 6 people can mow a lawn in 4 hours.
6 people minus 4 people is 2 people.
