Tyree and four friends go to the movies. each person buys a movie ticket for $7,a snack for $5,and a drink for $2. write an expression for the total cost of the trip to the movies. then find the total cost

Tyree and all of his friends get 1 ticket for $7. Next they all get 1 snack for $5. Then they all get a drink for $2. So:
1=7
1=5
1=2

Then you take each person (which there are five of then) and you times all five people by 7, 5, 2.

5 x 7=35
5 x 5=25
5 x 2=10

 After that you add it all together:

35 plus 25=60
60 plus 10=70
