He will use 1232 ounces in two weeks.
There are 7 days in a week so 2 weeks is 14 days. If he uses
5.5 pounds in 1 day, he will use 77 pounds in 2 weeks because
5.5 * 14 is 77 But then you will need to make it into ounces, so
Times 77 by 16 (Because there are 16 ounces in a pound) and you
will get 1232 ounces.
