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

• $0.50x+20=35$

• $0.50x=35$

• $0.50+20x=35$

• $0.50x-20=35$

Aliyah had $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost?

•  $24+10=7x$  

•  $24+7x=10$  

•  $10+7x=24$  

•  $10+x=14$

Last season, I spent $2752 to see my team play 43 games. To see each game, I had to buy a ticket and pay $10 for parking. How much was each ticket?

• $10\left(x+43\right)=2752$

• $x\left(10+43\right)=2752$

• $43\left(x+10\right)=2752$

• $2752\left(43+x\right)=10$
