Question

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

Answer 1

Answer:

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
