Answer:
34g
(second option listed)
Explanation:
half life is the number of days it takes to decrease by half,
after 8 days you are left with half of the original portion
in a period of 32 days, we experience 4 repeats of 8 days
(it gets cut in half four times):
544 / 2 = 272 {<em>day 8</em>}
272 / 2 = 136 {<em>day 16</em>}
136 / 2 = 68 {<em>day 24</em>}
68 / 2 = 34 {<em>day 32</em>}
so, after 32 days, 34g of ooblek are left un-decayed
hope this helps!! have a lovely day :)
