so she has 300 bucks, and the costs are 127 + 75, 202, plus the show entrance fee of 20 bucks per head.
so for 1 person is 20(1), for 2 is 20(2) bucks, for 3 is 20(3) and for "x" persons is 20(x) or 20x.
[tex]\bf \stackrel{\textit{in her pocket}}{300}~~\ge~~\stackrel{costs}{202 + 20x}\implies 300-202\ge 20x
\\\\\\
98\ge 20x\implies \cfrac{98}{20}\ge x\implies \cfrac{49}{10}\ge x\implies 4\frac{9}{10}\ge x[/tex]
so, she can only pay for 4 whole persons, now including herself that'd be her and 3 cousins then.
