Answer:
C.12
Explanation:
Let the number of fishes caught by Jack = j
Naomi caught half as many fish as Jack, therefore:
• The number of fishes caught by Naomi = j/2
Together, they caught 18 fishes:
[tex]j+\frac{j}{2}=18[/tex]We solve for j.
[tex]\begin{gathered} \frac{3j}{2}=18 \\ 3j=18\times2 \\ j=\frac{36}{3} \\ j=12 \end{gathered}[/tex]The number of fishes caught by Jack is 12.
C is the correct choice.
