Penelope is going to the carnival to ride the rides. It costs $20 to get into the carnival and ride tickets, x, are $0.50 each.
Write and solve an equation that represents this scenario if she spends $35 in all.

• 35 = 0.50x + 20

  x = 30 ride tickets

• 35 = 0.50x

  x = 30 ride tickets

• 35 = 0.50 + 20x

  x = 1.725 ride tickets

• 35 = 0.50x - 20

  x = 110 ride tickets

• 35 = 0.50x + 20

  x = 110 ride tickets
