Answer:
7.92%
Step-by-step explanation:
Given the following
Weight of package at home = 20.2 ounces. 
Weight of the package at the office = 18.6ounces
Decrement = 20.2 - 18.6
percentage error = decrement/wt at home * 100
percentage error = 1.6/20.2* 100
percentage error = 160/20.2
percentage error = 7.92
HEnce  the percent error in the weight of the package is 7.92%

We can re arrange this:
(-5)*(4) * x^6 * x * x^8 * y * y^6 * z^9 * z^9
using exponent properties
we can get
-20 x^15 y^7 z^18
as our simplified answer.
