Answer this question:Connie redeemed all her arcade tickets today. She spent half of them on a stuffed koala bear. She spent 10 tickets on a pair of earbuds. She spent another 15 tickets on glow bracelets. How many tickets did Connie redeem today?
Connie spent 10 tickets on earbuds + 15 tickets on glow bracelets = 25 tickets. Since Connie spends half of her tickets on a stuffed koala bear, that means the 25 tickets she spent on earbuds and glow bracelets is the other half, so she spent 25 tickets on the stuffed koala bear. In all, Connie spent 25 tickets on earbuds and glow bracelets + 25 tickets on a stuffed koala bear = 50 tickets.
The answer is 50.
