Answer 1

$700 for a chair and a table

Explanation:

Let t and c represent the price of a table and a chair, respectively. The given relations are ...

10c = 4t

15c +2t = $4000

Divide the first equation by 2 and substitute for 2t:

5c = 2t

15c +5c = $4000

20c = $4000

c = $200

t = 5c/2 = 5($200)/2 = $500

The total price of a chair and a table is ...

$200 +500 = $700 . . . . price of a chair and a table
