Wipes

The mummy wiped out the square wipes, and the veil was next to each other on the cord stretched out between the two trees. She used a cord of 7.5 meters in length, requiring about 8 dm on each side of the trunk. All wipes are 45 cm wide. The mummy leaves a gap of at least 10 cm between the wipes and the trunk. The clothes do not overlap and do not have them folded. How many wipes can hang up on a stretched cord?

Correct answer:

n =  12

Step-by-step explanation:

$$\begin{gathered} n=(7.5-2\cdot 0.8-2\cdot 0.1)/0.45 \\ n\approx 12 \end{gathered}$$
