To determine the cases of oil can you get from a 25 drum of oil:
Step 1: 1 gallon = 4 quarts
Hence from 25 gallon oil drum, 25 x 4 = 100 quart-size bottles can be filled.
Step 2: One case will pack 6 quart size bottles.
[tex]\begin{gathered} 1\text{ gallon}\Rightarrow\text{ 4 quarts} \\ 25\text{ gallon }\Rightarrow\text{ 25 x 4 = 100 quarts} \end{gathered}[/tex]
1 case will pack 6 quarts
[tex]\begin{gathered} 1\text{ case }\Longrightarrow\text{6 quarts} \\ x\text{ case }\Longrightarrow\text{ 100 quarts} \\ 6x=100 \\ x=\frac{100}{6} \\ x=16.67\text{ cases} \\ x\approx17\text{ cases} \end{gathered}[/tex]
Therefore number of cases from a 25 drum of oil = 17 cases of oil
Hence the correct answer is Option B
