Stock market 3

Because of a political crisis, the country's stock market index dropped by 600 points. Before the crisis, the country's stock market was performing well at 8,000 points. By how many percent did the country's stock market index points drop?

Correct answer:

p =  7.5 %

Step-by-step explanation:

$p=100\cdot \frac{600}{8000}=\frac{100\cdot 600}{8000}=\frac{60000}{8000}=\frac{15}{2}\%=7.5\%$
