Step-by-step explanation:

Calculating the Number of Teens Owning Cell Phones

To find out how many teens own cell phones in a class of 250 students, when 78% of teens reported owning a cell phone, we can apply a percentage calculation. Here's how:

  1. Understand that 78% of teens can be expressed as 0.78 when calculating.
  2. Multiply the percentage (as a decimal) by the total number of students in the class, which is 250 in this case: 0.78 * 250.
  3. The result will give you the number of teens who own a cell phone: 195 teens.

So, in a class of 250 students, an estimated 195 students would own a cell phone, based on the survey's reported percentage.
