Question

If the population of a town grew 11% up to 5,173, what was the population last year?

Answer 1

The answer is Population = P (?)

P+ P(0.11) = 5,173

P+ 0.11P = 5,173

1.11P = 5,173

1.11P/1.11 = 5,173 /1.11

P=5,173 /1.11

P=4,660

The last population was 4,660

4660 + 11% (That is equal to 512.6) = 5,173

Answer 2

to find this answer, you would need to find 11% of 5,173 and subtract it. to find 11%, you would use the expression 5,173 x 0.11, which is 569.03, which we can round to 569. 5,173 - 569 = 4604. so last year, the population in that town was 4,604 people.
