Question

you decide to market your own custom computer software. you must invest $3,255 for computer hardware, and spend $2.90 to buy and package each disk. if each program sells for $13.75. how many copies must you sell to break even?

Answer 1

Amount of money that needs to be invested for computer hardware = $3255
Amount of money needed to buy and pack each disk = $2.90
Let us assume the number of disks that need to be sold to break even = x
Cost at which each program sells = $13.75
Then
3255 + 2.90x = 13.75x
13.75x - 2.90x = 3255
10.85x = 3255
x = 300
From the above deduction, we can conclude that 300 disks need to be sold to break even. I hope the procedure is clear enough for you to understand.
