Answer:
$399.68
Step-by-step explanation:
The computation of X is shown below:
X = X ÷ (1 + 0.08)^10 + $1,000 ÷ (1 + 0.08)^20
= X ÷ 2.158925 + 214.548207
X - X ÷ 2.158925 = 214.548207
2.158925X - X ÷ 2.158925 = 214.548207
1.158925X = 214.548207 × 2.158925
X = 2.14548207 × 2.158925 ÷ 1.158925
= $399.68
