If each table costs twice as much as a chair, we can consider a table as 2 chairs.
So $170.10 = 2 tables + 5 chairs
Or $170.10 = 9 chairs
Each chair will cost (170.10/9) = 18.9;
A table is twice that cost, so its $37.8
So $170.10 = 2 tables + 5 chairs
Or $170.10 = 9 chairs
Each chair will cost (170.10/9) = 18.9;
A table is twice that cost, so its $37.8
