THIS IS DUE IN 10 MINUTES! You have 2 different savings accounts. For Account​ A, the simple interest earned after 15 months is ​$6.56. For Account​ B, the simple interest earned after 18 months is ​$14.40. If the interest rate is 3.5​% for Account A and ​2.4% for Account​ B, how much is the principal in each​ account? Which account earned you the most interest the first​ month? Explain your answer.

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal or initial amount of money invested.

R represents interest rate

T represents time

Considering the investment on account A,

I = $6.94

R = 3.7%

T = 9 months = 9/12 = 0.75 years

6.94 = (P × 3.7 × 0.75)/100 = 0.02775P

P = 6.94/0.02775 = $250

Considering the investment on account B,

I = $13.80

R = 2.3%

T = 18 months = 18/12 = 1.5 years

13.8 = (P × 2.3 × 1.5)/100 = 0.0345P

P = 13.8/0.0345 = $400

To determine the account that earned more interest in the first month,

250/9 = $27.8

400/18 = $22.2

Account A earned you the most interest the first​ month because $27.8 is higher than $22.2

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
