A concert has student tickets for $5 and adult tickets for $10. If a total of 255 tickets were sold, generating revenue of $2,275, how many adult tickets were sold?

Answer 1

5S+10A =2275

S+A = 255

5S+5A = 5(255) = 1275

subtract last equation from first

5A = 1000

A = 1000/5 = 200 Adult tickets sold

S = 255-200 = 55 Student tickets sold

check the answer

5(55) + 10(200)

=275 +2000

= 2275
