Answer:
- Cost of chair is $ 9
Given:
- Cost of table is four times as the chair
- Total cost of a table and four chairs is $18
Solution:
Let the cost of chair = $ x
then the cost of table = $ 4x
ATQ
→ 4x + 4x = $ 18
→ 8x = 18
→ x = 18/8
→ x = $ 2.25
Therefore cost of chair = x = $ 2.25
and, cost of table = 4x = $(4 × 2.25) = $ 9
