Clotheslines

Mommy needs six clotheslines 360 cm long. Clotheslines are sold in the length of eight meters. How many of these clotheslines must buy mom if any does not want to be connected? How much does mommy pay for the clotheslines when one piece costs 24kč?

Correct answer:

n =  3
x =  72 Kc

Step-by-step explanation:

$$\begin{gathered} k=\lfloor 800/360\rfloor =2 \\ n=6/k=6/2=3 \end{gathered}$$

$x=24\cdot n=24\cdot 3=72\text{Kc}$
