ANSWER
EXPLANATION
e have a 32 ounce bottle of weed killer concerntrate.
The directions say to mix 2 1/2 ounces of weed killer to water to make a gallon.
To find out how many gallons we will b able to make, we have to divide the total amount of the weed killer by the amount it takes to make one gallon.
That is:
[tex]\begin{gathered} \frac{32}{2\frac{1}{2}} \\ \Rightarrow\text{ }\frac{32}{\frac{5}{2}} \\ \Rightarrow\frac{32}{5}\cdot\text{ 2 = 12.8 }\cong13 \end{gathered}[/tex]They can make 12.8 (approximately 13) gallons of the weed killer.
