90 = the service charge per month

Answer:
2
Step-by-step explanation:
Given that the concentration has been modeled by the formula:
C(t)=50t/(t^2+25)
where:
t is time in hours.
The concentration after 5 hours will be given by:
t= 5 hours
plugging the value in the equation we get:
C(5)=(50(5))/(5^2+25)
simplifying the above we get:
C(5)=250/(50)=5 mg/dl
Answer: 5 mg/dl
Well i can't really help you in this since i do not know the cost of each calendar, but if you need the formula.
the cost of one calendar = x
so the total cost would be 200 times x (200x)
18 * 5 = 90
90 represents 100%, because there are 5 20% in 100%
In total there are 90 club members
80% = 71 do not have birthdays in the summer.
