Carmen runs a video to dvd transfer business. she charges her customers $20.40 for each video transferred. her expenses include $1,250.00 for the equipment and $2.45 for each blank dvd. which of these equations could carmen use to calculate her profit, p, for the transfer of n videos?

a. p = $17.95n - $1,250.00

b. p = $1,250.00 - $17.95n

c. p = $20.40n - $1,247.55

d. p = $22.85n + $1,250.00

A. p = $17.95n - $1,250.00

Step-by-step explanation:

Profit (p) = net revenue - expenditure

Net revenue = charge for transfer of n videos - expense for n blank DVD

charge per video transfer = $20.40

charge for n video transfer = $20.40 × n = $20.40n

expense per blank DVD = $2.45

expense for n blank DVD = $2.45 × n = $2.45n

Net revenue = $20.40n - $2.45n = $17.95n

expenditure = $1,250.00

Therefore, p = $17.95n - $1,250.00

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
