Answer: Let's call the initial goal amount of canned goods "g". The expression to represent the total percent of the goal collected can be written in two different ways as follows:
The first expression represents the initial goal plus the additional 18% collected over the weekend:
Total percent collected = g + 0.18g = 1.18g
This means that the volunteers collected 118% of the initial goal.
The second expression represents the ratio of the total amount collected to the initial goal:
Total percent collected = (g + 0.18g) / g = 1 + 0.18 = 1.18
This means that the volunteers collected a total of 118% of the initial goal.
