$x=3$
3 people went bowling.The shoe rental is $2.50$ whereas the cost per game is $5.30$. We know that $55.20$ was spent in total. Thus; $3\times5.3(x)+3(2.5)=55.2$ (simplify) $15.9x+6.5=55.2$ (multiply both sides by 10 so it can be easier to solve) $159x+75=552$ (subtract 75 from both sides) $159x=477$ (divide both sides by 159 to isolate the variable) $x=3$ Thus, 3 games were played.
