Penalty success increase

Maroš, the captain of the football team Coyotes from Kojetín, converted 15 penalties out of 20, so he has a success rate of 75%. How many percentage points will his success rate increase if he converts the following 5 penalties without hesitation?

Final Answer:

p =  5 pb

Step-by-step explanation:

$$\begin{gathered} p_1=100\cdot \frac{15}{20}=\frac{100\cdot 15}{20}=\frac{1500}{20}=75 \\ {p}_2=100\cdot \frac{15+5}{20+5}=80 \\ p=p_2-p_1=80-75=5\text{pb} \end{gathered}$$
