Answer:
4 lbs
Step-by-step explanation:
To determine what weight would make the cost the same for each company, we need to set these equations equal to each other. So,
2.5x+2.45=2.75x+1.45
To solve for x, we need to subtract 1.45.
2.5x+2.45=2.75x+1.45
-1.45 -1.45
Our equation is now 2.5x+1=2.75. Now, we have to subtract 2.5x from each side to then divide.
2.5x+1=2.75x
-2.5x -2.5x
The new equation is 0.25x=1. Now we can multiply 4 to find x.
0.25x*4=1*4
And you should get x=4 lbs.
