Answer:
20%
Step-by-step explanation:
1000×120%=1200
120-100=20
4+b
Set A is a function
set B is not a function
3a+2(4a-b)=
3a+8a-2b=
9514 1404 393
A = 4, B = 3
You require that ...
0.30 × A = 0.40 × B
Then ...
B = (3/4)A . . . . . divide by 0.40
Any pair of numbers that satisfies this equation will be possible values of A and B. One such pair is (A, B) = (4, 3).
