Answer 1

To calculate the total cost for each number of pizzas delivered, we can use the formula:

\[
\text{Total Cost} = (\text{Number of Pizzas} \times \text{Cost per Pizza}) + \text{Delivery Fee}
\]

Given that the cost per medium pizza is 10 dollars and the delivery fee is 5 dollars, we can fill in the table as follows:

1. For 1 pizza:
\[
\text{Total Cost} = (1 \times 10) + 5 = 10 + 5 = 15
\]

2. For 2 pizzas:
\[
\text{Total Cost} = (2 \times 10) + 5 = 20 + 5 = 25
\]

3. For 3 pizzas:
\[
\text{Total Cost} = (3 \times 10) + 5 = 30 + 5 = 35
\]

4. For 4 pizzas:
\[
\text{Total Cost} = (4 \times 10) + 5 = 40 + 5 = 45
\]

5. For 5 pizzas:
\[
\text{Total Cost} = (5 \times 10) + 5 = 50 + 5 = 55
\]

Now, we can fill in the table:

| Number of pizzas | Total cost in dollars |
|------------------|-----------------------|
| 1 | 15 |
| 2 | 25 |
| 3 | 35 |
| 4 | 45 |
| 5 | 55 |
