In a sample of 100 randomly selected concert attendees, the concert organizers find that 11 of them left the show early. the concert originally had 2,040 attendees.

a. use proportional reasoning to estimate how many of the total number of attendees left the concert early.

b. suppose there are 3 concerts at this hall next week, and the total attendance will be 5,500. use a percent expression to predict the number of these attendees who will leave a concert early next week.

A) ≈22.4 concert attendees might have left early.

B) 605 attendees might leave early.

Step-by-step explanation:

A) 11/100, or 11%, of the sample left early.

    11% of all the concert attendees is (11/100) × 2040 ≅ 22.4

    attendees who might have left early.

B) 11% of the total attendance is 11% × 5500 = 605 attendees who might

    leave early.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.
