Transmission Oils import engine oil.

They sell one brand of engine oil at `2 1/4` times the wholesale price.

If the wholesale price is $12 per litre, what is the selling price per litre?  (2 marks)

`$27\ text(per litre)`

Show Worked Solution

`text(Wholesale price) = $12\ text(per litre)`

`text(Sale price)` `= 2 1/4 xx 12`
  `= 9/4 xx 12`
  `= 9 xx 3`
  `=27`

 
`:.\ text(The selling price per litre)\ = $27`
