we thought the answer was 440. 1320/6=220. Then 1320-220=1100. then 1100/5=220. then subtract 1100-220=880 nd so on...does that make sense?

well of course it's not $330. He gets paid less than $1 for each cubic foot, and he only moved 220 ft^3. When you get an answer, the first thing to ask yourself is: Does it make sense? 220 ft^3 * $0.75/ft^3 = $165 Somehow you came up with twice the value you needed.

the amount left after t days is 220 (1/2)^(t/24) so, 220(1/2)^(168/24) = 1.718g 168 days is 7 half-lives, so 1/128 remains.
