A discount store is selling 5 small tables with 8 chairs for $115. Three tables with 5 chairs cost $70.
1)Which system of linear equations could be used to find the cost of each table (x) and the cost of each chair (y)?
A. 3x + 8y = $70; 8x + 3y = $115
B. 5x + 8y = $115; 3x + 5y = $70
C. 5x + 8y = $115; 2x − 5y = $70
D. 8x + 5y = $115; 5x + 3y = $70
2) Determine the cost of each table (x) and the cost of each chair (y).
A. x = $15; y = $5
B. x = $10; y = $5
C. x = $5; y = $10
D. x = $12; y = $3
.
1) B. 5x + 8y = $115; 3x + 5y = $70
2) D. x = $12; y = $3
