Kaylis [27]

Given:

Current population = x

The population of a city is expected to decrease by 6% next year.

To find:

The expression that represents the expected population next year. ​

Solution:

We have,

Current population = x

Decrease rate = 6%.

Expected population next year = Current population - 6% of Current population

                                                    =x-\dfrac{6}{100}x

                                                    =x-0.06x

                                                    =0.94x

Therefore, the expression for the expected population next year is 0.94x.
