If x is the number of floor seat tickets and y is the number of balcony tickets the inequality would be: [tex]15x + 5y \geqslant 75[/tex] And you can just plug it in to find if it would be enough [tex]15(3) + 5(4) \geqslant 75[/tex] [tex]45 + 20 \geqslant 75[/tex] [tex]65 \geqslant 75[/tex]
Since 65 is not greater than or equal to 75 you will not qualify
