The population in 2020 will be 57657.5 approximately

<u>Explanation:</u>

Given:

Population in 2014, P = 62,500

Rate of decrease, r = 1.6%

Population in 2020, Q = ?

Number of years between 2014 to 2020 = 5 years

Population in 2020 = P(1 - \frac{r}{100} )^t

Substituting the value we get:

Q = 62500(1- \frac{1.6}{100})^5\\ \\Q = 62500 ( 0.92252) \\\\Q = 57657.46

Therefore, the population in 2020 will be 57657.5 approximately

To conserve water, many communities have developed water restrictions. The water utility charges a fee of $38, plus an additiona
earnstyle [38]

Using a linear function, the correct option regarding the situation is given by:

C) 57 ≤ 1.28x + 38 ≤ 87; To stay within the range, the usage should be between 14.8 and 38.3 HCF.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

The bill is modeled by a linear function, with an <u>intercept of $38 and a slope of $1.28</u>, hence it is given by:

C(x) = 1.28x + 38

The bill should be between $57 and $87 dollars per month, hence:

57 <= C(x) <= 87.

The values of x are:

C(x) >= 57

1.28x + 38 >= 57

x >= 19/1.28

x >= 14.8.

C(x) >= 87

1.28x + 38 >= 87

x >= 49/1.28

x >= 38.3.

Hence option C is correct.
