Step-by-step explanation:
this equation has 3 steps
1. to find out how much the dvds cost without any discount or tax: $40
2. the price of the dvds with the 20% discount, which can be found with cross-multiplication making the price after discount $32

40 x 0.0675 = 2.7
40 x 0.8 = 32
32 + 2.7 = 34.7
