Answer
A. -30 points 
B. 60 points 
Step-by-step explanation:
20 points for correct answer and 10 points deducted for wrong answer 
Each deduction is -10 while each correct answer gives + 20
4 questions correctly and 11 incorrectly 
= 4(20) + 11(-10)
= 80-110 = -30 points 
Second round
7 correct, 8 incorrect 
= 7(20) - 8(10)

75,000 divided by 150, is 500, meaning they allow 500 people per acre. 500 times 145 is 72,500, meaning the capacity for a park your size should be 72,500 people.
        
             
        
        
        
G = gallons     d = days
10g = 3d
?g = 1d
1g = ?d
-------------
for gallons in a day, divide 10g = 3d by 3
d = 10/3 gallons
3 and 1/3 gallons in a day
---------------
for days per gallon, divide 10g = 3d by 10
g = 3/10 days
1 gallon lasts 3/10 of a day
