The population of a certain town this year is 12480. If the rate of increase of the population is 4%, what was previous year's population?​

The previous year's population was 12000.

Step-by-step explanation:

Let the previous year's population be P.  Then:

P + 0.04P = 1.04P = 12480.

Solving 1.04P = 12480 results in P = 12000

The previous year's population was 12000.

Step-by-step explanation:

12480*4/100

= 1248* 0.4

=499.2 is 4% of 1280

:. 1280 - 499.2

780.8 is previous year's population

idk this answer sorry cant on this one.

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
