Question

At Ron’s Roller Rink, the number of customers has been decreasing at a steady rate of 5% per year. If there were 900 skaters per week in 2000, what is a good estimate for the number of skaters per week in 2006?

Answer 1

Based on this information...  there should be about 630 skaters in 2006.  I hope this helps.

Answer 2

Answer:

The estimated number of skaters per week is 662.

Step-by-step explanation:

Given,

The number of skaters per week in 2000 = 900,

Also, it is decreasing at a steady rate of 5% per year,

So, the number  of skaters per week after x years since 2000,

$A=900(1-\frac{5}{100})^x$

$=900(1-0.05)^x$

$=900(0.95)^x$

For 2006, x = 6,

Thus, the number of skaters per week in 2006 is,

$A=900(0.95)^6$

$=661.582701563$

$\approx 662$
