Annual Rate = 16% = 16/100 = 0.16
Monthly Rate = (annual rate)/12
Monthly Rate = (0.16)/12
Monthly Rate = 0.01333 ... this is approximate

Finance Charge = (Monthly Rate)*(Previous Balance)
Finance Charge = (0.01333)*(179.32)
Finance Charge = 2.3903356
Finance Charge = 2.39

The purchases and payments do not factor in the finance charge since they are made during this current billing cycle. The previous balance method only looks at the balance at the end of the previous cycle. 

Once the finance charge is calculated, we add on the new purchases and the finance charge to the old balance. We also subtract off the payments/credits. Doing all this calculates the new balance for this billing cycle. 

New Balance = (Old balance) + (Purchases) + (Finance Charge) - (Payment)
New Balance = 179.32 + 117.42 + 2.39 - 85
New Balance = 214.13

In summary, 
Finance Charge = $2.39
New Balance = $214.13

Jessica has saved $50. She will add $25 to her savings each week. Ron has saved $40 and will add $25 to his savings each week.
MAVERICK [17]

Answer:

Jessica will have saved $175, and Ron will have saved $165.

Step-by-step explanation:

Jessica starts out with $50. She adds $25 each week, and it's asking how much money she would have in 5 weeks. So, you multiply $25 by 5 to get $125. Then, you add $50 to that to get $175. Same thing for Ron. Multiply $25 by 5 to get $125, but this time add $40 to it to get $165.

Solve the equation by completing the square x^2-3x-18=0
Alexandra [31]

Answer:

x = -3, 6

Step-by-step explanation:

First, add 18 to both sides

x² - 3x - 18 = 0

           + 18    + 18

x² - 3x = 18

Add 9/4 to both sides because that is the square of half of -3

x² - 3x + 9/4 = 18 + 9/4

Multiply both sides by 4 to get rid of the fractions

(x² - 3x + 9/4 = 18 + 9/4)4

4x² - 12x + 9 = 72 + 9 = 81

Factor the left side of the equation

(2x - 3)² = 81

√(2x - 3)² = √81

Because of the square root, this will result in a positive number and a negative number

2x - 3 = 9

2x - 3 = -9

For both equations, add 3 to both sides then divide by 2

2x - 3 = 9

     + 3   +3

2x = 12

2x/2 = 12/2

x = 6

2x - 3 = -9

    + 3   + 3

2x = -6

x = -3

a teacher invested $600 in an account that paid 2% annual simple interest the teacher did not maker any additional deposits or w
horrorfan [7]

Answer:

$36.00

Step-by-step explanation:

The formula for simple interest is I = P x r x t where P is the principal amount, $600.00, r is the interest rate, 2% per year, or in decimal form, 2/100=0.02, and t is the time involved, 3....year(s) time periods. So t is 3....year time periods. To find the simple interest, we multiply 600 × 0.02 × 3 to get that the interest is $36.00 . Usually now, the interest is added onto the principal to figure some new amount after 3 year(s), or 600.00 + 36.00 = 636.00.
