Kacey had 48 tickets for games at the school carnival. She used 1/3 of her tickets to play the spin-the-wheel game. She used half of the remaining tickets to play balloon game, where do you want eight more tickets. How many tickets did Casey have after paying these two games?

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
