Rohit visited a pumpkin patch with his family. The table shows the relationship between the weight and price of a pumpkin.

\begin{tabular}{|c|c|}
\hline \multicolumn{2}{|c|}{Pumpkin Patch Sales} \\
\hline Weight (lb) & Price (\[tex]$) \\
\hline 4 & 6 \\
\hline 8 & 12 \\
\hline 12 & 18 \\
\hline 16 & 24 \\
\hline 20 & 30 \\
\hline
\end{tabular}

Which statement describes the slope of a graph of the data?

A. For each additional pound, the price increases \$[/tex]0.50.
B. For each additional pound, the price increases \$1.50.
C. For every additional dollar, the pumpkin can increase by 1.5 pounds.
D. For every additional dollar, the pumpkin can increase by 0.5 pounds.



Answer :

To determine the correct statement that describes the slope of a graph of the data showing the relationship between the weight and price of pumpkins, let's analyze the data:

Given data:
[tex]\[ \begin{array}{|c|c|} \hline \text{Weight (lb)} & \text{Price (\$)} \\ \hline 4 & 6 \\ \hline 8 & 12 \\ \hline 12 & 18 \\ \hline 16 & 24 \\ \hline 20 & 30 \\ \hline \end{array} \][/tex]

First, we need to calculate the slope, which in this context is the rate of change of price with respect to weight. This is commonly given by the formula:
[tex]\[ \text{slope} = \frac{\Delta \text{Price}}{\Delta \text{Weight}} \][/tex]

We can choose any two consecutive points from the data to calculate the slope. Let's use the first pair of data points:
[tex]\[ \text{Weight}_1 = 4 \, \text{lb}, \, \text{Price}_1 = \$6 \][/tex]
[tex]\[ \text{Weight}_2 = 8 \, \text{lb}, \, \text{Price}_2 = \$12 \][/tex]

The change in weight ([tex]\(\Delta \text{Weight}\)[/tex]) is:
[tex]\[ \Delta \text{Weight} = \text{Weight}_2 - \text{Weight}_1 = 8 - 4 = 4 \, \text{lb} \][/tex]

The change in price ([tex]\(\Delta \text{Price}\)[/tex]) is:
[tex]\[ \Delta \text{Price} = \text{Price}_2 - \text{Price}_1 = 12 - 6 = 6 \, \text{\$} \][/tex]

Now we can calculate the slope:
[tex]\[ \text{slope} = \frac{\Delta \text{Price}}{\Delta \text{Weight}} = \frac{6 \, \$}{4 \, \text{lb}} = 1.5 \, \frac{\$}{\text{lb}} \][/tex]

This means for each additional pound, the price increases by \[tex]$1.50. Thus, the correct statement is: For each additional pound, the price increases \$[/tex]1.50.
