Answer:
Complete function will be 
Step-by-step explanation:
We have given equation 
We have to find the function in place of blank space and complete the function
We know the algebraic equation 
So 
So in place of blank pace there will be 
And complete function will be 
First option is the correct answer
Hey, I can answer in the comments but you need to have the boxes down in the picture if you can tell me the multiple degrees it has in the boxes then I can help thx :)
2x + y = 350
x + 2y = 475
3x + 3y = 825
x + y = 275
x = 275 - y
(plug back into first equation)
2(275 - y) + y = 350
550 - 2y + y = 350
550 - y = 350
-y =-200 or y = $200 (dog)
therefore, x = $75 (cats)
Check
2(75) + 200 = 350
75 + 400 = 475
HAPPINESS! :)
