Answer 1

A.

Cost of basket in 2006 = 250*10 + 600*4 + 400*6 = $7300

Cost of basket in 2007 = 250*12 + 600*5 + 400*5.5 = $8200

Cost of basket in 2008 = 250*15 + 600*5 + 400*7 = $9550

Cost of basket in 2009 = 250*18 + 600*6 + 400*9 = $11700

B.

% change in cost of basket between 2006-2007 = (8200-7300)/7300 = 12.3%

% change in cost of basket between 2007-2008 = (9550-8200)/8200 = 16.5%

% change in cost of basket between 2008-2009 = (11700-9550)/9550 = 22.5%
