Company 5

The Photo-Lab company offers digital photo development in the size 9 × 13 cm for 2 CZK per photo, with a flat handling fee of 50 CZK added to each order (regardless of the number of photos). Calculate the effective price per photo if we order 1, 5, 20, or 100 photos.

Final Answer:

a =  52 Kc
b =  12 Kc
c =  4.5 Kc
d =  2.5 Kc

Step-by-step explanation:

$$\begin{gathered} n_1=1 \\ f=2\text{Kc} \\ p=50\text{Kc} \\ a=\frac{f\cdot n_1+p}{n_1} \\ a=f+p/n_1=2+50/1=52\text{Kc} \end{gathered}$$

$$\begin{gathered} n_2=5 \\ b=f+p/n_2=2+50/5=12\text{Kc} \end{gathered}$$

$$\begin{gathered} n_3=20 \\ c=f+p/n_3=2+50/20=4.5\text{Kc} \end{gathered}$$

$$\begin{gathered} n_4=100 \\ d=f+p/n_4=2+50/100=2.5\text{Kc} \end{gathered}$$
