x=3

$3 x 5.30(x) + 3(2.50) = 55.20 $ $15.90x + 7.50 = 55.20$ $15.90x + 7.50 - 7.50 = 55.20- 7.50$ $15.90x = 47.90$ $15.90x \div 15.90 = 47.70\div 15.90$ $x = 3 $ Three friends go bowling. Their costs include shoe rental (2.50 per person) and cost per game (5.30). They spent 55.20 in all. To find the number of games played, set up the equation to include all costs for the 3 people and set it equal to 55.20.
