A discount store is selling 5 tables with 8 chairs for $115. Three tables with 5 chairs cost $70. Which system of linear equations could be used to find the cost of each table (x) and the cost of each chair (y)?
5x + 8y = 115; 3x + 5y = 70
5x + 8y = 115; 2x − 5y = 70
3x + 8y = 70; 8x + 3y = 115
8x + 5y = 115; 5x + 3y = 70
