11 students wore blue jeans
Given that , For the choir concert, the choir director has asked that everyone either wears black pants or blue jeans.
Three times as many students wore either black pants as blue jeans.
Let the number of students who wore blue jeans be n.
Then the number of students who wore black pants will be 3n
Now if there are 44 students is choir, we have to find how many wore blue jeans
As total students = 44
Students with blue jeans + students with black pants = 44
n + 3n = 44
4n = 44
n = 11
So, 11 students wore blue pants.
Then, 3n = 3 x 11 = 33 students wore black pants.
Hence, 11 students wore blue jeans
