12
You want to find an equivalent ratio with 2:3. As the question already gives you 8 where 2 used to be, you need to find out what change occurred to get from 2 to 8 (a multiplication of 4). To find the missing part of the ratio, multiply 4 with 3 to get 12.

Stells [14]


The pre tax cost of the four DVDs  will be:

4 × 9.99 = 39.96

 6.75% tax will amount to 6.75/100 × 39.96 →.0675 × 39.96 = 2.697 or 2.70 rounded off.

Cost of  DVDs after tax will be 39.96 + 3.70 = 42.66 $

20% discount will  be 20/100 × 42.66 →0.2 × 42.66 = 8.53 $

Cost of DVDs with 20% discount  will be 42.66 - 8.53 = 34.13

Rounded off  to the nearest cent, the total cost of the order is 34 $ and 10 cents.
