For finding the strength of the capsules after one year, we will use half-life formula. The formula is:
A = A₀ 
where, A= Final amount
A₀ = Initial amount
t= time elapsed
h= half-life
Here, in this problem A₀ = 10000 milligram, t= 1 year or 365 days
and h= 28 days
So, A = 10000 
⇒ A = 10000 
⇒ A = 1.187
So, the strength of the capsules after one year will be 1.187 milligrams.
For finding the solution, you want to sum the revenue from each class of paying customers. There were 92-40 who were over 12 years and paid $48, so the revenue from those folks is (92-40)·48. This term is found in the first and last selections only.
There were 40-x customers who were in the age range 3–12 years, so paid $36 each. The revenue from them is (40-x)·36. This term is found in the last selection only.
The appropriate choice is ...
... D.) (40 - x)·36 +(92 - 40)·48 = C
The first thing you would do is simplify the inside of the parenthesis to 55/6 using PEMDAS. Next all you do is multiply that by 5 to get 275/6 or 45.833 (repeating) in decimal form.
Answer:
1,520,000 liters of water
Step-by-step explanation:
4x10^4= 40000. 38x40000=1,520,000
1.52x10^6
Total = 242 + 307 = 549 but 242 ordered salad
so
242 / 549 = 0.4408 = 44.08%
answer
C. 44.08%
