11-74.

Add the interest he earns to his initial principal to find the total amount he would have after 5 years.

*I* = ($2000)(.1)(5 years)*I* = $1000

Total = $2000 + $1000 = $3000

*A* = 2000(1 + 0.8)^{5}

(1.08)^{5} = 1.469

*A* = $2000 (1.469) = $2938.66

Which account has more money after 5 years?
