Based on the table, what is the unit rate for one gallon of gasoline?

\begin{tabular}{|c|c|}
\hline \multicolumn{2}{|c|}{ Gasoline } \\
\hline Number of gallons & Price \\
\hline 2 & [tex]$\$[/tex] 6.60[tex]$ \\
\hline 3 & $[/tex]\[tex]$ 9.90$[/tex] \\
\hline 4 & [tex]$\$[/tex] 13.20[tex]$ \\
\hline
\end{tabular}

A. $[/tex]\[tex]$ 3.30$[/tex]
B. [tex]$\$[/tex] 4.60[tex]$
C. $[/tex]\[tex]$ 5.60$[/tex]
D. [tex]$\$[/tex] 6.50$



Answer :

To determine the unit rate for one gallon of gasoline, we need to calculate the price per gallon for each entry in the table.

Given:
- 2 gallons cost \[tex]$6.60 - 3 gallons cost \$[/tex]9.90
- 4 gallons cost \[tex]$13.20 Let's calculate the unit rate for each of these quantities: 1. For 2 gallons: \[ \text{Unit price} = \frac{\$[/tex]6.60}{2 \text{ gallons}} = \[tex]$3.30 \text{ per gallon} \] 2. For 3 gallons: \[ \text{Unit price} = \frac{\$[/tex]9.90}{3 \text{ gallons}} = \[tex]$3.30 \text{ per gallon} \] 3. For 4 gallons: \[ \text{Unit price} = \frac{\$[/tex]13.20}{4 \text{ gallons}} = \[tex]$3.30 \text{ per gallon} \] Since the unit price is consistent across all amounts, the unit rate for one gallon of gasoline is: \[ \$[/tex]3.30 \text{ per gallon}
\]

Thus, the correct answer is [tex]\(\$3.30\)[/tex].
