Answer:
cost of 1 shirt= $12
Explanation:
Let the cost of 1 shirt= $ x
and the cost of 1 tie= $ y.
Now according to the given statements we have:
6 shirts and 3 ties cost $79.50
i.e. 6x+3y= 79.50------(1)
Also
3 shirts and 2 ties cost $41
i.e. 3x+2y= 41-------(2)
Now on solving equation (1) and equation (2) by the method of elimination we will get the value of 'x' and 'y'.
First multiply equation (2) by 2 and subtract (1) by (2) to obtain:
6x+4y=82
6x+3y=79.50
- - -
------------------------
y=2.5
Hence, on putting the value of y in equation (2) we get:
3x+2Ă—(2.5)=41
3x+5=41
3x=41-5
3x=36
x=12 (on dividing both side by 3)
Hence cost of 1 shirt= $12
and cost of 1 tie= $2.5
