Answer:
A
Step-by-step explanation:
Let 
x = the number of phone available
If it would require 8 more phones, then the total number of phones will be x + 8.
A company hired an additional 12 employees, and every employee needed a phone, then
x + 8 = 12
x = 4
This means 4 phones were available (and 8 more needed to total in 12 phones for 12 new employees)
Hence, correct option is option A.

The teacher would need 40 centimeters of tape to hang 10 student projects.
Step-by-step explanation:
Given, 
Tape used to hang projects = 36 centimeters
Number of projects hanged = 9 
We will find unit rate;
9 projects = 36 centimeters
1 project = 
1 project = 4 centimeters
Therefore, 
Tape needed to hang 10 projects = 4*10 = 40 centimeters
The teacher would need 40 centimeters of tape to hang 10 student projects.
