Step-by-step explanation:
Make a commone demonatore my multiplying.
So you know the school donated 9 pies, so you want to know how many pieces are in 9 pies. (remember 8 pieces per 1 pie)
9 x 8 = 72
Next you subtract the amount you got to total amount.(224)
So 224 - 72 is 152.
152 is how many pieces of pie were sold by students.
To configure this number back to amount of pie, you basically need to divide by 8(number of pieces in 1 pie).
152 divided by 8 is 19. So 19 pies were sold by students.
Hope this helped!

<u>Arithmetic Sequences</u>
The arithmetic sequences can be identified because each term is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
Here a1 is the first term and r is the common difference.
The given sequence is:
We can find the common difference by subtracting successive terms:
Since all the differences are equal, r=6. Thus, the general term is:
Operating:
The nth term is:
