The percent decrease was 20%
Step-by-step explanation:
In order to find this, use the percent change equation.
(New - Old)/(Old) * 100 = % Change
Now input 48 for the New price and 60 for the Old price.
(48 - 60)/(60) * 100 = % Change
12/60 * 100 = % Change
.2 * 100 = % Change
20 = % Change

Answer: n= -20?
Step-by-step:
Simplify both sides of the equation
1/5n+4=0
Then subtract 4 from both sides
1/5n + 4 - 4 = 0 - 4
1/5n= -4
Then multiply both sides by 5
5*(1/5n)=5*(-4)
