hey guys I want to know how to do it as well so I know how to do it on the test :)

Average = 17.65 years

Step-by-step explanation:

It is given that,

35% of the people in a class are 17 years old.

65% of the people in a class are 18 years old.

We need to find the average age for the students in the class.

Let there are 100 people in the class. It means that 35 people are 17 years old and 65 people are 18 years old.

Sum of ages of people having 17 years age = 35 × 17 = 595

Sum of ages of people having 18 years age = 65 × 18 = 1170

So,

So, the average age for the students in the class is 17.65 years.
