Gilberto Bartlett · Answer 1

A decrease of 6% means that 94% are still in the club each year so the formula is

A = 300 (0.94) ^t where t is the number of years

After 5 years number of members = 300 (0.94) ^5 = 220 Answer

Virginia Kennedy · Answer 2

6 percent of 300 = 18

18 * 5 = 90

300 - 90 = 210 within 5 years
