Answer:
The 35 pound bag
Step-by-step explanation:
If you divide the price of the 25 pound bag by the number of pounds it has you get 0.81 dollars per pound
20.25 / 25 = 0.81
However if you divide the price of the 35 pound bag by the number of pounds it has you get 0.79 dollars per pound
27.65 / 35 = 0.79
This means you get more dog food for less in the larger 35 pound bag

Answer:
<em>x = -2, y = -1</em>
Step-by-step explanation:
<u>System of Equations</u>
Solve the system:
y = 1/2x
y = -x - 3
Multiplying the first equation by 2:
2y = x
Substituting x in the second equation:
y = -2y - 3
Adding 2y:
3y = -3
y = -3/3
y = -1
And x = 2*(-1) = -2
Solution: x = -2, y = -1
