Answer:

202.5

Step-by-step explanation:

\frac{L}{45} = \frac{90}{20} → \frac{L}{45} = \frac{9}{2}

9 x 45 = 405 → 2L=405

L=\frac{405}{2} → L = 202.5

A town has a population of 13000 and grows at 2.5% every year. What will be the population after 5 years, to the nearest whole n
vova2212 [387]

Answer:

The population will be 14708

Step-by-step explanation:

formula

A = P (1+r)^t

Initial population = P = 13000

Growth rate = r = 2.5% = 0.025

Number of years = t  = 5 years.

A = 13000 (1+.025)^5  = 14708
