He buys 20 tickets for $45.
Val is buying tickets for the amusement park.
The total cost of the tickets varies directly with the number of tickets purchased.
She sees that 12 tickets cost $27.
The cost per ticket is given by;
[tex]\rm = \dfrac{Total \ cost \ of \ tickets }{Total \ number \ of \ tickets}\\\\= \dfrac{27}{12}\\\\= 2.25[/tex]
Therefore,
The number of tickets can Val buy for $45 is;
[tex]\rm =\dfrac{Total \ number \ of \ tickets}{Cost \ of \ per \ ticket}\\\\= \dfrac{45}{2.25}\\\\= 20[/tex]
Hence, he buys 20 tickets for $45.
