Answer:
60% chance a girl is picked
Step-by-step explanation:
There is 10 students in total. 6 out of 10 are girls. We can represent this in a fraction 6/10. Now we convert the fraction into a percentage 60%.
Prices changed from 100% price to 80% price due to sale.
100% - 20% = 80%
THEN increased by 25% so
80% + 25% = 105%
so the overall effect is that the price rose from the original (100%) to 105%
so a 5% increase
