SOLUTION
From the table you sent, you got all except one of them.
Let me show you the one you didn't get
For every 8 photos, the printer takes 4 minutes, so 9 minutes the printer prints
[tex]\begin{gathered} 8\text{ photos }\rightarrow4\text{ minutes } \\ x\text{ photos }\rightarrow9\text{ minutes } \\ 8\rightarrow4 \\ x\rightarrow9 \\ \text{cross multiplying, we have } \\ 8\times9=4\times x \\ 72=4x \\ \text{divide through by 4} \\ \frac{72}{4}=\frac{4x}{4} \\ x=\frac{72}{4} \\ x=18 \end{gathered}[/tex]
Hence the one you didn't get, the answer is 18
