You decide to market your own costume computer software. You invest $3255 for computer hardware, and spend $2.90 to buy and pack
age each disk. If each program sells for $13.75, how many disks must you sell to break even?(use x and y for your variables).
1 answer:
3255+2.60x=13.75x
2.60x-13.75=-3255
-11.15x=-3255
x=-3255/-11.15
x=291.9 or 292 disks need to be sold to break even.
