Answer:
The 12 pack has a better value.
Step-by-step explanation:
1. create a ratio table.
you want to know how much the 4 pack would cost if it was a 12 pack.
you can see the ratio table in the picture above.
As you can see, when the 4 pack equals $7.68, making it a 12 pack will equal $23.04.
<em>Then</em><em>,</em><em> </em><em>compare</em><em> </em><em>2</em><em>3</em><em>.</em><em>0</em><em>4</em><em> </em><em>to</em><em> </em><em>2</em><em>2</em><em>.</em><em>3</em><em>2</em><em>.</em><em> </em>
<u>In</u><u> </u><u>conclusion</u><u>,</u><u> </u><u>the</u><u> </u><u>1</u><u>2</u><u> </u><u>pack</u><u> </u><u>has</u><u> </u><u>a</u><u> </u><u>better</u><u> </u><u>value</u><u>.</u>
To express the volume of both trucks in a single expression, we add the expressions,
8x² + 2x - 1
and also,
7x² - 2x + 1
Adding the corresponding terms in the expressions will give us an answer of,
15x²
Thus, the volumes of the trucks in a single expression is 15x².
