Understanding Percentages in Class Projects

The video tutorial explains how to determine the value of a class project worth 20% of a total 800 points. It demonstrates two methods: converting the percentage to a decimal and multiplying by the total, and using the percent equation. Both methods confirm the project is worth 160 points.

What is the total number of points available in the class?

• 800

• 700

What is the result of multiplying 0.2 by 800?

• 120

• 140

• 160

• 180

Which equation represents the percent equation method?

• percent + base = amount

• percent - base = amount

• percent / base = amount

• percent * base = amount

In the percent equation method, what does the variable 'a' represent?

• The total

• The percentage

• The base

• The amount

What is the base value used in the percent equation method?
