Answer:
b. more money
Step-by-step explanation:
Randy's original position lets him make:
50*500 = $25,000
The new position will let him make:
$27,500
Therefore,
original position < new position = $25,000 < $27,500

Answer:
Expected population in 2015: 19,152.58 or 19,000 people
Step-by-step explanation:
Given the decreasing rate of 2.5% per year, and a population of 28,000 in the year 2000:
We can solve for the rate of decrease by using the formula:
![A = a(1 - r )^{t}](https://tex.z-dn.net/?f=A%20%3D%20a%281%20-%20r%20%29%5E%7Bt%7D)
where:
A = population by year 2015
a = initial population (in year 2000) = 28,000
r = rate of change (decrease by 2.5% annually or 0.025)
t = time (in number of years) = 15
Plug in these given values into the formula:
![A = a(1 - r )^{t}](https://tex.z-dn.net/?f=A%20%3D%20a%281%20-%20r%20%29%5E%7Bt%7D)
![A = 28,000(1 - 0.025 )^{15}](https://tex.z-dn.net/?f=A%20%3D%2028%2C000%281%20-%200.025%20%29%5E%7B15%7D)
![A = 28,000(0.975)^{15}](https://tex.z-dn.net/?f=A%20%3D%2028%2C000%280.975%29%5E%7B15%7D)
A = 28,000(0.684)
A = 19,152.58 or about 19,000 people in 2015
We will find the rate of Greg and Josh earning money that is
the amount of money they receive per unit time (hour)
Since the trip is in 3 weeks,
Number of hours Josh worked = 3 weeks * (5 hours/week) = 15
hours
Number of hours Greg worked = 3 weeks * (8 hours/week) = 24
hours
Josh’s rate = $480/15 hrs = $32/hr
Greg’s rate = $480/24 hrs = $20/hr
Therefore
Josh makes $12/hr more than Greg
First add the times she went over the the 3 months
So she went 6 monthsin total
Multiply that by 10 so equals 60
Alison will take 60 bags of cans to the recycling center in these three months.
