Ninety percent of a town’s population owns cars. if the number of cars owned is 4761, what is the population of the town?

We can write an equation of this, with p representing the unknown population. We know that 90% of the population owns cars:

90% * p

We also know that 4761 people own cars, which is the same as the above expression, so we write:

90% * p = 4761.

From there, you just divide both sides by 90%, or 0.9

p = 4761/0.9 = 5290

The population is 5290 people.

Write an equation. Use x for the population of the town.

90% of the population is the same as 90% of x.

To change a percent into a decimal, divide the percent by 100.

90/100 = 0.9, so 90% is the same as 0.9.

Now we write an equation.

0.9x = 4761

Divide both sides by 0.9:

x = 4761/0.9

x = 5290

The population of the town is 5290.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
