A town has a population of 72,700 and grows at a rate of 3.5% every year. Which equation represents the town’s population after

Allushta [10]

Answer:

for 4 years: $72,700 + 1.035^4(72,700)$

For n years: $72,700 + 1.035^n(72,700)$

Step-by-step explanation:

Since each year the growth rate is 3.5 of the last year, n will represent the number of years.

$72,700 + 1.035^n(72,700)$

Therefore since n is 4, the equation will be:

$72,700 + 1.035^4(72,700) =72,700 + 1.15(72,700)$

Therefore this equation represents the town after four years.
