The club shop sold a box of golf b***s for $20.40 .

The shop made a profit of 20% on the cost price.

 

Calculate the cost price of the golf b***s.

Cost price + .20* Cost price  = $20.40

 

Cost price ( 1 + .20)  = $20.40     divide both sides by (1 + .20)  = (1.20)

 

Cost price  = $20.40 / 1.20  = $ 17

 

 

cool cool cool
