Question

the owner of the \cd universe\ website just bought 1000 cds by the same musical artist. cd universe decides to sell them to its customers for $12.95 each. what formula could be use profit/loss, p, for selling n cds?
a. $p = 12.95n + 6450$
b. $p = 6450 - 12.95n$
c. $p = -6450 - 12.95n$
d. $p = 12.95n - 6450$
please select the best answer from the choices provided
a
b
c
d

Explanation:

Step1: Understand Profit Formula

Profit (\(p\)) = Revenue - Cost. Revenue from selling \(n\) CDs at \$12.95 each is LXI2. Assume the cost of buying 1000 CDs is \$6450 (since \(1000\times6.45 = 6450\), likely the cost per CD is \$6.45, total cost \$6450).

Step2: Derive Profit Formula

So, \(p=\text{Revenue}-\text{Cost}=12.95n - 6450\). This matches option d.

Answer:

d. \( p = 12.95n - 6450 \)
