Down at Bikini Bottom, Spongebob is 90% water and weighs 10 ounces. On dry land, he is only 80% water. How much does Spongebob weigh now on dry land? Show your solution and also show why your solution does or doesn't make sense.
this is what I worked out, please let me know if I did something wrong...
if 90%=10
then 10%= 10/9
so 80%=90%-10%=10-1.1= 8.9oz
