Which statement is modeled by the expression? The Perez family drove 500 miles each day of their vacation. If their vacation lasted for n days, then 500n is the total number of miles they traveled on their vacation. The community theater had a capacity of 500 seats. If n is the number of tickets sold for a performance, then 500n is number of seats that were left empty for that performance. Jody had 500 dollars in her savings account. She withdrew n dollars to buy some camping supplies. She then had 500n dollars left in her savings account. A store had 500 apples to be placed in bags with an equal number of apples in each bag. If n is the number of bags to be used, then 500n is the number of apples in each bag..

Vavilen inflated a huge balloon in 19 minutes. Then he poked a hole in the balloon so that it slowly leaked air out until it was completely deflated.The rate at which the air leaked out of the balloon (in liters of air per minute) was half of the rate at which Vavilen inflated the balloon. It took the balloon 38 minutes to completely deflate.At what rate did Vavilen inflate the balloon, and at what rate did the balloon deflate?

Which statement is modeled by the expression? 100p One hundred more players signed up for soccer than the league had planned for. The league had p uniforms in stock. The number of uniforms the league needs to buy to make up the difference is 100p . Each player in the league was given 100 tickets to sell. If there are p players in the league, the total number of tickets to sell is 100p After the league had supplied each player with a uniform, there were 100 uniforms left over. If there are p players in the league, 100p is the number of uniforms the league had originally. The coach received 100 tokens for the amusement park rides. If there are p players on the team, each player will receive 100p tokens.
