Answer:

Step-by-step explanation:

Let x be the number of friends.
He wants to give out 2x bars and have 10 left and he has 16 bars so the expression is:-
2x + 10 = 16
now he can solve for x to find the number of friends he can treat.
( a ) The system of equations:
2 r + b = 8.403 r + b = 9.35( b ) Graph is in the attachment.
( c ) Each item costs:
b = $6.50, r = $0.95We can prove it: 2 * 0.95 + 6.50 = 8.40
3* 0.95 + 6.50 = 9.35
