To calculate growth rate, start by subtracting the past value from the current value. Then, divide that number by the past value. Finally, multiply your answer by 100 to express it as a percentage.
<u>Explanation:</u>
The "population growth rate" is the rate at which the number of individuals in a population increases in a given time period, expressed as a fraction of the initial population. Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.
Annual Growth Rate of Population refers to the rate at which the number of individuals in a given popular increase over a year, expressed as a fraction of the initial popular of the previous years. The annual percentage growth rate of population is the percent growth divided by the number of years.
You can't solve this unless you have numbers to substitute or another equation.
Answer:
$21.10=3.10+2m.
Step-by-step explanation:
If the total fare was $21.50, then that is what it will all have to equal out to.
They charged a pick-up fee of $3.10. Which means that no matter how far you go, you will pay that. Then an extra $2 per mile. If m is mile, then it would be 2m because it is $2 per extra mile. Then add the pick-up fee of $3.10 and you will get your answer of $21.50=3.10+2m.
The answer to both equations is 'A'. For the first you just input the value of 20 to replace n and get 700. (Side-note: the number 20, which is your variable, should be nowhere in the function so you know b is wrong). so now that you have your answer 700 the second part is self explanatory.
