FroYo Express charges $5.75 for a large cup of frozen yogurt and $0.25 for each topping. The Big Chill charges $2.75 for a large cup of frozen yogurt and $1.25 for each topping.
The graph represents the relationship between the number of toppings, x, and the total cost of a large cup of frozen yogurt, y, at the two stores.

For what total cost are the number of toppings the same at both stores?

• The total cost is $3.00 when the number of toppings is the same at both stores. 

• The total cost is $6.50 when the number of toppings is the same at both stores. 

• The total cost is $5.75 when the number of toppings is the same at both stores. 

  
  

• The total cost is $2.75 when the number of toppings is the same at both stores.
