2. The restaurant bill you and your friend received was not itemized. You ordered 2 drink refills and the egg breakfast, for a total 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.
2r + b = 8.40
3r + b = 9.35
You order 2 refills and 1 egg breakfast, costing a total of $8.40. So your equation becomes:
2r + b = 8.40
Your friend ordered 3 refills and 1 egg breakfast, costing 9.35. So his equation is
3r + b = 9.35
