She showed the PC

Sabína wrote down how many hours a day she sat at the PC. Dana showed the situation with a radar graph. She was around 100% at the PC longer on weekends than on weekdays. Saturday-5 hours, Sunday-4 hours. And during the week it was: Monday 1 hour, Tuesday 0.5 hours, Wednesday 2 hours, Thursday 3 hours, Friday 2.5 hours.

Correct answer:

p =  150 %

Step-by-step explanation:

$$\begin{gathered} p_1=\frac{5+4}{2}=\frac{9}{2}=4.5\text{h} \\ {p}_2=\frac{1+0.5+2+3+2.5}{5}=\frac{9}{5}=1.8\text{h} \\ p=100\cdot \frac{p_1-p_2}{p_2}=100\cdot \frac{4.5-1.8}{1.8}=150\% \end{gathered}$$
