Answer:
0
Step-by-step explanation:
1. 0% can be written as 0/100, and "of" indicates we need to multiply 0/100 by 104.
Therefore, 0% of 104 is 0.
I beleive the system of equations would be:
a+b=4000
0.1a+0.04b=352
I cant say for sure because the question did not list the cost of a and b together but rather the number of both items together
1: 2x+y=3
5x-2y=12
2: Multiply the first equation by 2
(2) (2x+y=3) => 4x+2y=6
3: Add
4x+2y=6
+ 5x-2y=12
______________
9x=18 The y's cancel out
9x/9=18/9 The 9's cancel out
x=2
4: Plug (x=2) back into either equation but, I'm going to do the first one. It's easier.
2(2)+y=3
4+y=3
4-4+y=3-4 The 4's cancel out
y=-1
Answer: (12,-1)
If you plug (x) and (y) back in it will equal 3 for the first and 12 for the second.
Hope this helps
