500 tickets were sold for a concert. some cost $5 and some cost $8. the cash received for the expensive tickets was $100 more than the cheaper tickets. find the number of each kind of ticket which were sold.

200 $5 tickets sold, and 300 $8 tickets sold

Step-by-step explanation:

x = # of $5 tickets sold

y = # of $8 tickets sold

     This is a simple system the first equation is x + y = 500. The next equation is y = x +100. Therefore you substitute the second equation into the first and get an answer of (200, 300) or 200 $5 tickets sold, and 300 $8 tickets sold.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4
