Answer:
$14,159.60
Step-by-step explanation:
Inflation-adjusted principal = Principal * (1+inflation)
Inflation-adjusted principal = 1,000,000 * (1+1.14%)
Inflation-adjusted principal = 1,000,000 * 1.0114
Inflation-adjusted principal = $1,011,400
Now, the coupon rate is given as 2.8% or 1.4% semi annually.
Coupon Payment = Coupon rate * Inflation-Adjusted Principal
Coupon Payment = 1.4% * $1,011,400
Coupon Payment = $14,159.60
Therefore, the first coupon payment is $14,159.60
