Question

Read the following description of a relationship:
To stay healthy, Bella runs 7 kilometers every day.
Let d represent the number of days and k represent the total number of kilometers Bella runs.
Complete the table using the function k=7d.
d k
1
2
3 21
4

Answer 1

To complete the table using the function \( k = 7d \), we will plug in the values of \( d \) for each day into the equation to find \( k \).

1. For \( d = 1 \):
\[
k = 7 \times 1 = 7
\]

2. For \( d = 2 \):
\[
k = 7 \times 2 = 14
\]

3. For \( d = 3 \):
\[
k = 7 \times 3 = 21 \quad \text{(already given)}
\]

4. For \( d = 4 \):
\[
k = 7 \times 4 = 28
\]

Now, we can fill in the table:

\[
\begin{array}{|c|c|}
\hline
d & k \\
\hline
1 & 7 \\
2 & 14 \\
3 & 21 \\
4 & 28 \\
\hline
\end{array}
\]

So the completed table is:

\[
\begin{array}{|c|c|}
\hline
d & k \\
\hline
1 & 7 \\
2 & 14 \\
3 & 21 \\
4 & 28 \\
\hline
\end{array}
\]
