Answer:
A = P x r^t
Step-by-step explanation:
A = Amount (e.g. number of organisms in population after certain period of time)
P = Principal/ Initial Value (e.g. the starting population)
r = rate as a decimal (e.g. if a population increases over certain period of time by 20%, r would equal 1.2)
t = time in whichever units you need.
Example of problem using formula:
A population of 2000 decreases by 20% every year, find the population size after 5 years.
A = ?
P = 2000
r = 0.8
t = 5
A = Pxr^t
A = 2000 x 0.8^5
A = 655.36

Answer:
$17225
Step-by-step explanation:
convert percent values to decimals
7.5/100=.075
plug into equations where x=total interest and y is total loan pay
1500*.075*2=x
1500+x=y
solve equation 1
1500*.075*2=x
225=x
solve equation 2 now that we know total interest
1500+225=y
17225
(i would appreciate a thanks and rating my boy)
Y = (x - 5)²
y = (x - 5)(x - 5)
y = (x² - 5x - 5x +25)
y = x² -10x + 25
Answer:
Total income= $498.32
Step-by-step explanation:
Giving the following information:
Fixed income= $340 on a weekly quota of $8000
Variable income= 4.74%on any sales above the quota
Sales= $11,340
<u>First, we need to structure the total income formula:</u>
Total income= 340 + 0.0474*x
x= sales over the quota
<u>Now, for actual sales:</u>
Total income= 340 + 0.0474*(11,340 - 8,000)
Total income= $498.32
