Given: C(N) = 15,000 + 8000N <span>
In the above equation simply substitute:
N(t) = 100t - 5t^2
for N
</span>
<span>Therefore:
C(t) = 15,000 + 8000{ 100t-5t^2 }
C(t) =15,000 + 800,000t - 40,000t^2.</span>
at t = 5
C(5) = 15,000 + 800,000*5
- 40,000*(5)^2
<span>C(5) = 3,015,000</span>
Answer: x = 2
Step-by-step explanation:
<em>first, we remove the parentheses. </em>
10 - 54 - 24x = 10x - 120 + 8
<em>then, we just calculate that out.</em>
-44 - 24x = 10x - 112
<em>next, we move the terms.</em>
-24x - 10x = -112 + 44
<em>then, we collect the like terms and calculate it.</em>
-34x = -68
<em>finally, we divide both sides.</em>
x = 2
The correct answer is 140 because the mean, average, number from July per day represents how many people would have visited each day if they were all even.
If there were 20 more people each day in August, the mean would be 140. This would represent how many people visited each day.
