Question

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

Answer 1

After each year, the number of units in use will decrease by 2%. To find the number of units in use after n years, use the equation 8000 * 0.98^n.

Step-by-step explanation:

After each year, the number of units that will be in use will decrease by 2%. This can be represented by the equation: 8000 * 0.98^n, where n is the number of years.

So, to find the number of units in use after n years, we substitute n into the equation. For example, if we want to find the number of units in use after 3 years, we replace n with 3:

8000 * 0.98^3 = 8000 * 0.941192 = 7529.54

Therefore, after 3 years, approximately 7529.54 units will be in use.

Answer 2

400 or 4/80 would be after n years
