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

Eliminate

C) x = $5; y = $10

D) x = $12; y = $3

First one is A and the second one is B

Marcos Barnett · Answer 2

1) B and 2) A

Step-by-step explanation:

40x+25y=575

-40x-24y=-560

adding

y=15

5x+3 (15) = 70

then

5x+45=70

5x=25

x=5

Answer: x=5 and y=15
