The correct answer is B.
Answer:
C) 5000(0.987783)^t
Step-by-step explanation:
The monthly interest rate is the APR divided by 12, so is 22%/12 ≈ 0.018333.
Each month, the previous balance (B) has interest charges added to it, so the new balance is ...
balance with interest charges = B + (22%)/12×B = 1.018333×B
The minimum payment is 3% of this amount, so the new balance for the next month is ...
balance after payment = (1.018333B)(1 - 0.03) = 0.987783B
Since the balance is multiplied by 0.987783 each month, after t payments, the balance starting with 5000 will be ...
5000×0.987783^t . . . . . . . . . matches choice C
Factor out 12x^3y^2
12x^3y^2(3y^2+5x^ 2 y z^2 -1)
A) multiply by 2 both sides, canceling the ÷ by 2
4x - 1 = 2x + 14
+1
4x = 2x +15
-2x
2x. = 15
÷2
x = 7.5
B) mutiply 3 both sides
9x + 6 = 2x + 13
-6
9x. = 2x + 7
-2x
7x. = 7
÷1
x = 1
