Question

can someone help with financial algebra

Answer 1

Okay, so the interest rate that the problem is asking for is actually going to be the increase in y and x.
This is also known as slope.
You'll notice as you increase in x value, your y value also increases

Answer 2

the problem should clarify simple or compound interest. but simple is a good enough assumption to me.

Answer 3

Actually you can look at it like this :

At year 0, Jason's balance was 1218
In 4 years, his balanced increased to 1412.6
1412.6 - 1218 = 194.6 increase over a 4 year span
194.6/4 = 48.65 increase over a 1 year span
His balance increased by 48.65$ each year

Answer 4

I'm sorry but my brain decided to shut down for the night...I can't help you any more... Brain farts suck :(

Answer 5

I understand that aspect but how will that lead to the answer?

Answer 7

Okay here we go, I had to review real quick.

So we're going to use two amounts
The first amount was Jason's initial investment
At year 0 he had $1,218
After 4 years of interest he had $1,412.60

Acquired amount means the amount you have after receiving your interest.
Jason's acquired amount would be $1412.60

Initial amount means the amount you have before receiving your interest.
His initial amount would be $1218

Time means the length of time we are dealing with (4 years)

rate = (1/time) (Acquired Amount/Initial Amount - 1)
r = (1/t)(A/P - 1)
Let's plug the numbers in
r = (1/4) (1412.6/1218 - 1) Solve this
r = 0.03994253
Convert r to a percentage
r* 100 = 3.99% per year
Round that up to 4% and there's your answer

Answer 8

A rare bacterial culture is being grown in a lab. As the days progress, the cells multiply and grow.

After 1 day, there is only 1 cell.
After 2 days, there are 9 cells.
After 3 days, there are 20 cells.
After 4 days, there are 34 cells.

Which recursive equation represents the pattern?

an = an – 1 + 3n
an = an – 1 + n + 2)
an = an – 1 + 3(n + 2)
an = an – 1 + (3n + 2)

Answer 9

I got the first one but I am not sure

Answer 10

the question marks btw are subtraction signs

Answer 11

I have no idea...Is that all the info they give you?

Answer 12

Yup
