Answer:
103 chairs
Step-by-step explanation:
cost = fee + cost per chair * number of chairs
410 = 100 + 3*c
Subtract 100 from each side
410-100 = 100+3c-100
310 = 3c
Divide by 3
310/3 = 3c/3
103.3=c
We cannot rent part of a chair so we round down
103 chairs

Answer:
<h3> Yes, but only if a=0 or b=0</h3>
Step-by-step explanation:
If you would like to know who is correct, you can find this using the following step:
<span>6x - 2 = -4x + 2
Spencer:
</span>6x - 2 = -4x + 2 /+4x
6x - 2 + 4x = -4x + 2 + 4x
10x - 2 = 2
Jeremiah:
6x - 2 = -4x + 2 /-6x
6x - 2 - 6x = -4x + 2 - 6x
-2 = -10x + 2
They both are correct. But in Jeremiah's version of solving the equation, we would have to multiply equation by -1 (or add 10x to both sides), which we don't have to do in the Spencer's version.
