**Damon**, Monday, May 30, 2011 at 8:04pmprice in first year =425

price in second year = 1.024 * 425

price in third = 1.024*1.024 * 425

so

A) price in n th year = 1.024^(n-1) * 425

price in 11 th year = 1.024^10 * 425

= 538.75

B) 2000 = 425 * 1.024^(n-1)

4.70588 = 1.0124^(n-1)

log 4.70588 = (n-1) log 1.024

n-1 = 65.3

n = in the 66 th year
