Rob notices that 55 percent of the people leaving the supermarket choose plastic bags instead of paper bags. Out of 600 people, how many can rob predict will carry plastic bags?
Well... First of all, 55% is equal to what as a fraction? 55/100! So them 100 is 100x6 so then we do 55x6. 100x6=600 and 55x6=330! So the answer/amount of people using plastic bags is 330 people!
