Answer:
$2147.36
Step-by-step explanation:
The first value can be modeled by ...
b1 = 1000·(1 -0.005)^t
After 10 years, that balance is ...
b1 = 1000·0.995^10 = 951.11
__
The second value can be modeled by ...
b2 = 1000·(1 +0.018/2)^(2t)
After 10 years, that balance is ...
b2 = 1000·1.009^20 = 1196.25
__
The total of the two investments after 10 years is ...
$951.11 +1196.25 = $2147.36
Answer: 0.167
