Answer:

r = 5q / (p + 10)

Step-by-step explanation:

p = 5(q - 2r)/r

multiply both sides by r

pr = 5(q - 2r)

distribute

pr = 5q - 10r

add 10r to both sides

pr + 10r = 5q

Factor out r

r(p + 10) = 5q

divide both sides by p + 10

r = 5q / (p + 10)

The population of a town is 81,712 and declines continuously at a rate of 4.1% each year. What is the approximate population of

Ganezh [65]

Data:

P (Final population) = ?
Po (Initial population) = 81712
r (rate) = 4,1% = 0,041
t (time in years) = 17

$P = Po - (Po*r*t)$
$P = 81712 -(81712*0,014*17)$
$P = 81712 - 56953.264$
$P =24758.736$
$\boxed{P \approx 24759}$

Answer:
B) 24759
