Please help I am stuck on this question You have 2 different savings accounts. For Account A, the simple interest earned after 21 months is $11.55. For Account B, the simple interest earned after 15 months is $12.00. If the interest rate is 3.3% 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.

PRINCPAL = A 3.33  B 4.76  

Account B had earned more interest month 1 = $0.80

Step-by-step explanation:

LCM of 21 and 15 = 105

Account A. = 21 months is $11.55 interest

Account B = 15 months is $12.00 interest

Account A = given 3.3% =  11.55 / 0.033 = 350 then 350/105 = 3.3333 = 3.33

Account B = given 2.4% = 12/ 0.024 = 500 then 500/105 = 4.76109 = 4.76

FIRST MONTH = 1 PART WORKINGS

Account A = 11,55/ 21 = $0.55

Account B = 12/15 = $0.80

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
