Answer

Explanation:

Step1: Analyze the expression

The expression (5(15+( - 3))) represents the net change in the number of residents over 5 years. Here, (15+( - 3)=15 - 3 = 12) is the net number of residents moving in each year (15 moving in and 3 moving out).

Step2: Calculate the total

Multiplying the net number of residents per year ((12)) by the number of years ((5)) gives (5\times12 = 60). This (60) represents the total net number of new residents in the suburb after 5 years.

Answer:

C. After five years, there are 60 new residents in a suburb.
