It would be Y=kx.
Look at photo for explanation
12 500- 1 250= 11 250
11 250 (divided by) 50= 225
Each student should raise 225 dollars
To simplify this, we need to do PEMDAS (parenthesis then exponents, then multiplication and division, then addition and subtraction). Here, we can't combine any like terms in the parenthesis. Since there's no exponents, that means that the next step is to do multiplication. This gives us:
3 - 15y - 21 + 2y - 6
Now we can combine like terms.
(-15y + 2y) + (3 - 21 - 6)
-13y - 24
I don’t know the gap at the beginning but the answer is c
