271/5 = 54.2 hours
How: 2/5 +2/5+3/5 times 5 (bc its 3 different dogs with different times for 5 days) +3 (for 3 dogs) times 4/5 (bc each dog take 4/5 of an hour each) + 1/5 (for the extra 1/5 of an hour pepper wanted to stay outside)

To be honest I do not know I am not that great at math but I can try
Regular pay:
45x40x17=30,600
Overtime:
45x6x17x1.5=2142
Total payroll= 30,600+2142=32,742
Total overtime/total payroll * 100 =
2142/32,742 *100 = 6.5%
The function that represents the number of E.coli bacteria cells per 100 mL of water as t years elapses, and is missing in the question, is:

Answer:
Option A. 59%
Explanation:
The base, 1.123, represents the multiplicative constant rate of change of the function, so you just must substitute 1 for t in the power part of the function::
Then, the multiplicative rate of change is 1.590, which means that every year the number of E.coli bacteria cells per 100 mL of water increases by a factor of 1.590, and that is 1.59 - 1 = 0.590 or 59% increase.
You can calculate it also using two consecutive values for t. For instance, use t =1 and t = 1

The volume of this box is indeed 84 in^3. What were you looking for beyond that?
Base: (7 in)(3 in) = 21 in^2
Height: 4 in
volume = (21 in^2)(4 in) = 84 in^3 (answer)
