Answer: 980 tickets
Step-by-step explanation:
A band sold out a concert that has 4,200 seats. A random sample of 120 ticket buyers was surveyed, and 28 buyers were found to have made their purchase on the first day the tickets were being sold. This means (28/120) = 7/30 of the 120 ticket were purchased on the first day.
To get the number of first day tickets purchased when 4,200 tickets are likely to have been purchased will be the fraction gotten multiplied by 4200. This will be:
= 7/30 × 4200
= 29400/30
= 980 tickets
