The answer is 90. you add them all up and divide it by 4
Answer:
(3x+5y)/8
Step-by-step explanation:
The total amount is 150+250=400
We then do (3x+5y)/2 × 1/400
This equals (3x+5y)/800
We multiply that by 100 giving us the final answer.
The answer is x is equal to 2.64

It is a positive-slope parabola with vertex of (0,16) "concave up"
