Question

The 4th grade class experienced a 15% decrease in enrollment. Last year, the 4th grade class had 280 students. How many students are enrolled in the 4th grade class this year?

Answer 1

Answer: 238

Step-by-step explanation: 15% of 280 is 42 so subtract 42 from the number and it equals 238

Answer 2

There are a lot of ways to solve this, but here is a simple one. 15% reduction gets you 85%, or 0.85 in decimal form. So you now know that this year’s 4th grade class is going to be 85% or 0.85 of what it was last year (280). Just multiply 280*0.85. 238 is your answer.
