So it is asking you to group like term so
x terms can be grouped/added/subtracted to other x terms, but not to x^2 or x^3 terms
x^2 terms to x^2 and so on so
1. 9-3k+5k=
9+(5k-3k)=
9+2k
2. k^2+2k+4k=
k^2+(2k+4k)=
k^2+6k=
Answer:
$10,880
Step-by-step explanation:
15% = 15 ÷ 100 = 0.15
So 15% of 12800 = 0.15 x 12800 = 1920

OR
12800 x (1 - 0.15) = 10880
