The city Music Hall charges $22.00 per adult and $10.00 per senior citizen. One day 461 people attended a concert. The total receipts this day were $6434.00. How many adults attended the concert? Your answer should be a number only.
Let "a" represent the number of adults attending. Then (461-a) is the number of senior citizens. Total receipts will be ... a*22 + (461-a)*10 = 6434 12a = 6434-461*10 a = 1824/12 = 152
The number of adults that attended the concert was ... 152
