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:
![a_n=-12+4(n-1)](https://tex.z-dn.net/?f=a_n%3D-12%2B4%28n-1%29)
Step-by-step explanation:
The generic formula for the n-th term of an arithmetic sequence is ...
an = a1 +d(n -1)
where an is the n-th term and a1 is the first term.
__
Here, you have a1 = -12 and d = 4. Putting these numbers into the formula gives you what you are asking for:
an = -12 +4(n -1)
3/5 / 3/7
= 3/5 * 7/3
= 7/5 or 1 2/7
