Answer:
667
Explanation:
Since x is inversely proportional to p then we can relate it as follows
x=k/p where k is constant of proportionality.
Making k the subject of formula, k=px
Given that when p is 5 and x is 800 then
K=5*800=4000
Now when p is $6 thwn x will be
X=k/p=4000/6=666.6666666666667
Rounded off, x=667 boxes
