roberta sold fifty tickets for the school play. Roberta sold ten more student tickets than adult tickets. How many tickets did roberta sell?

Answer 1

She sold 50 tickets. You already said that.

Answer 2

X-Adult tickets,
(x + 10) Student tickets.

x + (x + 10) = 50 tickets,
2x + 10 = 50,
2x = 50 - 10,
2x = 40,
x = 2o.

(x + 10) = 20 + 10 = 30.
