You need to rent a moving truck for a day. You have identified two companies that rent trucks. Company A charges $40 per day plus $0.10 per mile K Company B charges $30 per day plus $0.15 per mile. For how many miles will the cost of renting be the same?

To determine the number of miles where the cost of renting from both companies is the same, we can set up an equation that represents the total cost for each company and solve for the number of miles.

### Let:
- $ x $ represent the number of miles driven.
- Company A charges $40 per day plus $0.10 per mile, so the total cost for Company A is:
  \[
  C_A = 40 + 0.10x
  \]
- Company B charges $30 per day plus $0.15 per mile, so the total cost for Company B is:
  \[
  C_B = 30 + 0.15x
  \]

Now, set the two cost equations equal to find when the costs are the same:
\[
40 + 0.10x = 30 + 0.15x
\]

### Solve for $ x $:
1. Subtract $ 30 $ from both sides:
   \[
   40 - 30 + 0.10x = 0.15x
   \]
   \[
   10 + 0.10x = 0.15x
   \]

2. Subtract $ 0.10x $ from both sides:
   \[
   10 = 0.05x
   \]

3. Divide both sides by $ 0.05 $:
   \[
   x = \frac{10}{0.05} = 200
   \]

So, the cost of renting the truck will be the same when you drive **200 miles**.
