Answer:
Phased installation
Explanation:
The name of this strategy is phased installation. Phased installation (or phased implementation) occurs when an existing system is replaced by a new one. However, unlike most implementations, this takes place in stages. This has several advantages. First, it allows you to test the system. If there is a problem with it, it is easier to revert back to the old strategy. Moreover, if employees need to adopt this new system, it allows them to get used to it slowly while still being able to access the previous one.
The expression that can be used to represent the total amount Terri spent is C = 5 + 2x
<h3>How to write equation</h3>
- Cost of magazine = $5
- Number of nail polish bought = 2 bottles
let
x = cost of each nail polish
Total cost, C = magazine + nail polish
C = 5 + 2x
- If cost of each nail polish = $3
C = 5 + 2x
= 5 + 2(3)
= 5 + 6
C = $11
