The population of Mastertown is 23,000 in 2012.
Assuming a yearly increase of 2%, we can model future population with an exponential growth formula. Using the geometric sequence form gives:

A_n = A_1 * r^(n-1)

<span>Population = initial population in 2012 × 0.02^[(year - 2012) - 1]</span>

Answer: y = 23000 (1 + 0.02)^x

Step-by-step solution:

The population in 2012 is 23,000

The annual growth rate is 2%

Using the compound growth formula:

y = a(1 + r)^n

a = initial value

n = number of years

r = growth rate

Interpreting for population (y) after x years since 2012:

a = 23000

Growth rate 2%

r = 2/100 = 0.02

So the model is:

y = 23000 (1 + 0.02)^x

zzz [12365]
The set of rental car rates making it more economical for Jamal than employing taxi services is outlined as A = {x | 0 ≤ x < 26} [where x represents dollars]. The step-by-step breakdown is as follows: Let the rental cost be $x per day. With Jamal's trip extending over 4 days, factoring in $24 for gas, and estimating taxi costs at around $128, an inequality emerges: 128 > 24 + 4x. Thus simplifying leads to 4x < 104 and consequently x < 26.
