Students at Riley Middle School are attending a field trip. The entrance fee is $25 and the bus costs $10 per person. Write two equivalent expressions to find the cost for 20 students to attend the field trip. Find the total cost.



Answer :

Answer:

  • The total cost is $700

=====================

Each student spends $25 for entrance and $10 for travel.

If there are 20 students, then the total cost can be expressed as following.

1) 25*20 + 10*20 = 500 + 200 = 700

It means 20 people spend $500 for entrance and $200 for travel.

2) (25 + 10)*20 = 35*20 = 700

It means each person spends a total of $35 and all 20 spend $700.
