Question

A set of furniture contains one table and four chairs How much does one chair cost, if the table costs 80 dollars and the whole furniture set costs 200 dollars?

Answer 1

c = chair

200 = 80 + 4c

Subtract 80 from 200

120 = 4c

Divide 120 by 4

30 = c

200 = 80 + 4(30)

One chair costs $30
