The nation's nominal GDP does not take inflation into account. To solve this problem, we simply calculate the nation's nominal GDP in Year 4, ignoring the base prices. Keep in mind that if we were calculating real GDP, we would have to use the base year prices in our GDP calculation.

Televisions: 20 x 550 = 11,000 +
Total GDP =$48,400
Answer is C) 48,400
