The ideal decision is B

385

$0.5\times 1+1=1.5\phantom{\rule{0ex}{0ex}}1.5\times 2+2=5\phantom{\rule{0ex}{0ex}}5\times 3\times 3+3=18\phantom{\rule{0ex}{0ex}}18\times 4+4=76\phantom{\rule{0ex}{0ex}}76\times 5+5=385$

385

$0.5\times 1+1=1.5\phantom{\rule{0ex}{0ex}}1.5\times 2+2=5\phantom{\rule{0ex}{0ex}}5\times 3\times 3+3=18\phantom{\rule{0ex}{0ex}}18\times 4+4=76\phantom{\rule{0ex}{0ex}}76\times 5+5=385$
