Question

A city has a population of 51,368. If the population grows 1.8% each year, what will the
population be in 5 years (rounded the nearest whole number)?

Answer 1

Answer:

56,161

Step-by-step Thought Process:

Use the equation: $a(1+r)^x$ to solve this problem. Let x= time in years, a= initial amount, and r= growth rate.

$a(1+r)^x$ =  $51368(1+0.018)^5$

When you solve you get this number:

56,160.57516085

Round to the nearest whole number:

56,161
