Answer:
- as written, -57
- as perhaps intended, C. -11
Step-by-step explanation:
The expression shown evaluates as ...
7 + 32(-5 +1)/2 = 7 +32(-4)/2 = 7 -128/2 = 7 -64 = -57
_____
If we assume your "32" is supposed to be 3², or 3^2, then the expression evaluates differently:
7 +3²(-5 +1)/2 = 7 + 9(-4)/2 = 7 -36/2 = 7 -18 = -11 . . . . matches choice C
_____
When in doubt, you can have the Google calculator evaluate your expression. However, you do have to write it properly and with all the required parentheses.
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!
