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?
a. 778 skaters
b. 662 skaters
c. 695 skaters
d. 732 skaters

Given:
year 2000 - 900 skaters per week.

Decrease of 5% per year.

2000 - 900 x 52 weeks = 46,800
2001 - 46,800 x 95% = 44,460
2002 - 44,460 x 95% = 42,237
2003 - 42,237 x 95% = 40,125
2004 - 40,125 x 95% = 38,119
2005 - 38,119 x 95% = 36,213
2006 - 36,213 x 95% = 34,402

34,402 ÷ 52 weeks = 661.5 or  B. 662 SKATERS PER WEEK.

The answer would be option 4

The answer would be b ! explanation: the formula for sa *surface area * is 2×l×w+2×l×h+2×w×h so in this case l=4w=12h=8so you use the formula to solve it and it give you the answer of 352^cm^2
