You have 2 different savings accounts. For Account​ A, the simple interest earned after 18 months is ​$5.70. For Account​ B, the simple interest earned after 21 months is ​$16.10. If the interest rate is ​3.8% for Account A and ​2.3% for Account​ B, how much is the principal in each​ account? Which account earned you the most interest the first​ month? Explain your answer.

Answers

Answer:
Principal in account A = $200
Principal in account B = $600
Account B earned more interest in the first month.
Step-by-step explanation:
Given two accounts:
Account A:
Time = 9 months = years
Interest rate = 3.8%
Interest earned = $5.70
Account B:
Time = 27 months = years
Interest rate = 2.4%
Interest earned = $32.40
To find:
Principal in each account.
Most interest earned in the first month?
Solution:
First of all, let us have a look at the formula for Simple Interest.

Putting the values for Account A and finding the value of Principal:

Now, Putting the values for Account B and finding the value of Principal:

Interest earned in one month i.e. years:
Account A:


Account B earned more interest in the first month.
Therefore, the answers are:
Principal in account A = $200
Principal in account B = $600
Account B earned more interest in the first month.

Heres how. At first you ignore the exponent (you'll come back to it) 12x ÷ 6x = 2x. Then you have to solve with the exponent. 2 × 2 = 4 then add the label. 4x, and that's how you get the answer. Hope this helps.

Step-by-step explanation:

what is the answer for this questions
and explain why

Answers

Answer:

B

Step-by-step explanation:

Well you first know that your y-intercept is -2 (look on the graph) so you can automatically cancel out option A and D. Now this leaves us with B and C. The only thing that is different between the two answers is the slope. Slope = Δy/Δx (change in y divided by change in x) So from (0,-2) to the next point (4, -1) How far is the x and y? Well you go up one and to the right 4. the change in y is up one (+1) and the change in x is right 4 (+4).

You can also do this

\frac{-2-(-1)}{0-4} = \frac{-1}{-4} = 1/4\\

(y2-y1)/(x2-x1) (the numbers are subscripts)
