2. The restaurant bill you and your friend received was not itemized. You ordered 2 drink refills and the egg breakfast, for a t
otal of $8.40. Your friend ordered 3 refills and the egg breakfast for $9.35. (a) Write a system of equations for the situation. Use r for the amount charged for a refill and b for the amount charged for the egg breakfast.
(b) Graph the equations in the system.
(c) Use your graph to estimate how much each item cost.
( a ) The system of equations: 2 r + b = 8.40 3 r + b = 9.35 ( b ) Graph is in the attachment. ( c ) Each item costs: b = $6.50, r = $0.95 We can prove it: 2 * 0.95 + 6.50 = 8.40 3* 0.95 + 6.50 = 9.35
