An electronic games manufacturer producing a new product estimates the annual sales to be 8000 units. Each year 2% of the units
that have been sold will become inoperative. So, 8000 units will be in use after 1 year, [8000 0.98(8000)] units will be in use after 2 years, and so on. How many units will be in use after n years
I believe the answer is 7 since 8x squared is 64x and subtract 4x=60x 60x/16x multiplied by 5/x-5. but i am not sure since i do not know the value of X sorry buddy, just trying to help
