A town has a population of 4000 and grows at 3.5% every year. To the nearest year, how long will it be until the population will reach 7500?

18.273 years will take to reach the population of 7500, if a town has a population of 4000 and grows at 3.5% every year.

Step-by-step explanation:

The given is,

             Population of 4000

             Rate of grow 3.5% every year

             Population after few years 7500

Step:1

            Formula to calculate the population with the grow rate every year,

                                   ..........................(1)

           Where,

                    F - Population after t years

                   P - Initial population

                    r - Rate of grow

                    t - No.of years

          From given,

                  F = 7500

                  P = 4000

                   r = 3.5%

        Equation becomes (1),

                   1.875 =

       Take log on both sides,

       Substitute log values,

                             = 18.273

                          t = 18.273 year

                             or

                         t = 18 years 3 months 2 weeks

Result:

          18.273 years will take to reach the population of 7500, if a town has a population of 4000 and grows at 3.5% every year.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
