Sales of a new tablet grow by 10% every month. Sales for this month are at 5 thousand. Write an equation to represent this situation and then approximate the sales 6 months from now.

We start with the sale at $5,000. The growth is: p = 10% = 0.1; r = 1 + 0.1 = 1.1

The equation is:

f (t) = 5,000 * (1.1) ^t

where t it the time in months.

f (6) = 5,000 * (1.1) ^6 =

= 5,000 * 1.77156 = $8,857.80

Answer: The sale 6 months from now will be $8,857.80.
