To solve this problem, we need to calculate the total cost $ C $ for using the computer for $ t $ minutes. The information given includes:

- An initial charge of $10.
- An additional charge of $0.60 per minute.

### Step 1: Create an Equation
The total cost $ C $ can be written as:
\[
C = 10 + 0.6t
\]
where $ t $ represents the number of minutes of computer use.

### Step 2: Fill in the Table
Now we can use this equation to find the cost for different values of $ t $ as given in the table:

1. **For $ t = 0 $:**
   \[
   C = 10 + 0.6 \times 0 = 10
   \]

2. **For $ t = 1 $:**
   \[
   C = 10 + 0.6 \times 1 = 10 + 0.6 = 10.6
   \]

3. **For $ t = 2 $:**
   \[
   C = 10 + 0.6 \times 2 = 10 + 1.2 = 11.2
   \]

4. **For $ t = 3 $:**
   \[
   C = 10 + 0.6 \times 3 = 10 + 1.8 = 11.8
   \]

### Completed Table

| Number of Minutes ($ t $) | Total Cost to Use Computer ($ C $) |
|-----------------------------|--------------------------------------|
| 0                           | $10.00                               |
| 1                           | $10.60                               |
| 2                           | $11.20                               |
| 3                           | $11.80                               |

So, the completed table and equation $ C = 10 + 0.6t $ represent the total cost based on the number of minutes.

2. How does the total cost change with each additional minute of computer use?
3. Can you express the cost for 30 minutes of computer use using this equation?
4. What would the total cost be if the initial charge were $15 instead of $10?
5. How would the equation change if the per-minute charge were $0.75?

#### Tip:
Remember that in linear equations, the initial charge is the "y-intercept," and the per-minute charge is the "slope," showing how much the cost increases per minute.

Gianna is going to use a computer at an internet cafe. The cafe has an initial charge of $10 to use a computer and an additional charge of $0.60 for every minute of use. Make a table of values and then write an equation for C, in terms of t, representing the total cost of using a computer for t minutes at the internet cafe.
