Answer:
the cost of the three new CDs is $44.28
Step-by-step explanation:
Here in this question, we are interested in calculating the cost of 3 new CDs cost.
From the question, we already know the cost of one. The cost of three would be 3 multiplied by the cost of one.
The cost of the three excluding the sales tax = $13.79 * 3 = $41.37
The sales tax for the three pieces = 3 * $0.97 = $2.91
The cost of the three CDs including the sales tax = $41.37 + $2.91 = $44.28

Answer:
b = 2/7 or b = -1/2
Step-by-step explanation:
14b^2 - 2 = -3b
14b^2 + 3b - 2 = 0
14b^2 + 7b - 4b - 2 = 0
7b(2b + 1) -2(2b + 1) = 0
(7b - 2) (2b + 1) = 0
So, b = 2/7 or b = -1/2
