Answer :
ANSWER:
a. 39 qt
b. 9.75 gal
STEP-BY-STEP EXPLANATION:
The first thing is to know the conversion factor between gallons and quarts.
We know that 1 gallon is equal to 4 quarts, therefore:
a.
[tex]\begin{gathered} 9\text{ gal}\cdot\frac{4\text{ qt}}{1\text{ gal}}=36\text{ qt} \\ \text{ therefore:} \\ 36\text{ qt + 3 qt= 39 qt} \end{gathered}[/tex]b.
[tex]\begin{gathered} 3\text{ qt}\cdot\frac{1\text{ gal}}{4\text{ qt}}=0.75\text{ gal} \\ \text{ therefore:} \\ 9\text{ gal + 0.75 gal = 9.75 gal} \end{gathered}[/tex]
