Sonji went to a sandwich shop for lunch with 8 of her friends. Part of the group ordered only a sandwich for $5, and the rest of the group ordered a combo for $8. The bill for all 9 people totaled $66. 0. Which system of equations represents the number of meals of each type that Sonji and her friends purchased? x y = 9. 5 x 8 y = 66. X y = 66. 8 x 5 y = 9. X y = 66. 5 x 8 y = 9. X y = 9. 5 x minus 8 y = 66.

Respuesta :

We need to know about the system of equations to solve such problems.

Given to us

  • Sonji went to a sandwich shop for lunch with 8 of her friends.
  • Part of the group ordered only a sandwich for $5, and the rest of the group ordered a combo for $8.
  • The bill for all 9 people totaled $66.

Assumption

Let's assume that the number of sandwiches ordered is x and the number of combos ordered is y.

Total Orders

Given that the group of people was of 9 people, therefore, a total of 9 orders must be made.

Total number of orders =  number of sandwiches ordered + number of combo ordered

[tex]9 = x+y[/tex]

Total bill

total bill of the group

=(number of sandwiches ordered x cost of a sandwich ) + (number of combos ordered x cost of a combo)

[tex]66=5x+8y[/tex]

Hence, we got the two equations of the system.
