Question 368247: Please help me solve this word problem.
30 students bought pennants.
The plain pennants cost $4.
The fancy pennants cost $8.
The total cost if all pennants is $186.
How many fancy pennants were purchased?

Let P be the number of plain pennants, F fancy pennants.
Total number of pennants:
1.
Total value of pennants:

2.
Multiply eq. 1 by (-2) and add to eq. 2,

There is a problem with your problem setup.
The expected numbers for P and F are integers unless someone buys 1/2 of a pennant.
Please check the problem and re-post.
