Answer:
C) The rate of inflation is 29.17% in 2010.
Explanation:
the price of the basket in 2009 (base year) = ($20 x 6) + ($30 x 4) = $120 + $120 = $240
the price for the basket in 2010 = ($25 x 6) + ($40 x 4) = $150 + $160 = $310
inflation rate = [(CPI 2010 - CPI 2009) / CPI 2009] x 100 = [($310 - $240) / $240] x 100 = 29.17%
