Answer:
112.6471
Step-by-step explanation:
GDP deflator = nominal GDP in 2012 / real GDP in 2012 x 100
Nominal GDP in 2012 = current year prices x quantity produced
= ($2.50 x 15) + ($22 x 7) = $37.50 + $154 = $191.50
Real GDP in 2012 = base year prices x quantity produced
($2 x 15) + ($20 x 7) = $170
GDP deflator = $191.50 / $170 = 1.126471 x 100 = 112.6471
