You have to turn the percent into a decimal to do the math. 

80 * .40 = 32 (That's the discount.) Now we subtract the orginal price from this.

80 - 32 = 48

Now we need to find the tax value.

48 (our new price) *  .0675 = $3.24

Add this back onto the price to get our final price.

3.24 + 48 = $51.24
