Strategies for Maths Problem

If the cost a chair is $10 and the cost of table is $12. John spent a total amount of $232 for 22 chairs and table. How many chairs and table did he buy?


Method - Assumption


Assume he bought all tables 22x$12 = $264

Diff in total amt = $264-232 =32

Diff between chair and table = $2

Therefore no of chairs = 32/2 = 16 chairs
