Answer:
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 $66.00. 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
THEREFORE(A IS THE ANSWER)
