How to do the problem:
Assuming that you mean you want 12% of the number 80 and showing work, here is the answer:
To get X percent of any number, write the percent as a decimal and then multiply that decimal by the whole.
What I mean:
You want 12% of 80
so first change 12% into a decimal
12% is equal to .12 as a decimal
Then multiply that decimal by the whole
Since you want 12% of 80, 80 is the whole
that means you do .12 * 80
which is equal to 9.6
<u>Thus(answer)</u>
12% of 80 = 9.6
Simple interest is where 3% of the original value is added on each year
goal number = $102
original number = $680
3% of $680 can be found by getting 1% and multiplying by 3
100% = original number = $680
100% / 100 = 1% so $680 / 100 = $6.80 = 1%
3% = $6.80 * 3 = $20.40
so each year the money rises by $20.40
to find out how many years it would take to get to $102:
$102 / $20.40 = 5 years
Y = -3(2) +22
Y = -6 +22
Y = 16

Answer: years of equal population are 1995 and 2022.
in 1995, population was 425,000 people and in 2022, population was 1,910,000 people.
Step-by-step explanation: Baskinville: y = x2 - 22x + 350
Cryersport: y = 55x - 950
Note that x2 is xsquare not x2
Resolving the quadratic equations carefully will give the values of y and x which represent the population and years.
