Step-by-step explanation:

I don't know which answer option is which letter.

the right answer is the one top right with

-6x - 15y = -135

why ?

well, the second equation is unchanged to the original.

and the first equation is just the original first equation that was multiplied on BOTH, the left and the right side by the same factor : -3

therefore, its information and validity is unchanged compared to the original.

and so, this combination has the same solution as the original.

Answer:

The population will be 240,116

Step-by-step explanation:

Exponential growth can be represented by the expression:

$P(t) = P_i\,(1+r)^t$

where:

$P(t)$ is the population at time (t)

$P_i$ is the initial value of the population

"r" is the annual rate of growth (written in decimal form)

and "t" is the time in years.

Therefore in this situation, P(16) is what we want to find [the population after 16 years]

the initial population $P_i$ is 110,000

the rate of growth is 0.05 [decimal form of 5%]

and t is 16 years.

Replacing all these in the given functional form gives:

$P(t) = P_i\,(1+r)^t\\P(16)=110000\,(1+0.05)^16\\P(16)=240116$
