Sinusoid graphs look like regular waves.

Unit cost of a ticket = Income from ticket sales / number of tickets sold:
$1250
--------------- = $6.58 per ticket
190 tickets
Again:
$1175
--------------- = $6.71
175 tickets
While ticket prices do change (usually increase) from year to year, it's unusual to see such a situation here.
Don't have any guidelines by which to determine the "fixed cost of a ticket".
If we use the cost of a ticket of 2 years ago ($6.58/ticket), then the income from the sale of 225 tickets this year would be ($6.58/ticket)(225 tickets), or $1480.50.
3x - 7 = 2x - 5<em> add 7 to both sides</em>
3x = 2x + 2 <em>subtract 2x from borh sides</em>
<h3>x = 2</h3>
Check:
L = 3(2) - 7 = 6 - 7 = -1
R = 2(2) - 5 = 4 - 5 = -1
L = R CORRECT! :)
