In order to find the price per ticket, or unit rate, we need to divide 312 by 12
after this, we get 26. we know that unit rate is price PER 1 ticket.
Therefore, we get:
$26/ticket
X + (x+3) = 28
<span>2 x + 3 = 28 </span>
<span>2x = 25 </span>
<span>x = 12.5 </span>
<span>x+3 = 15.5
28-15.5= 12.5
The two lengths are 15.5 and 12.5. </span>
