Answer:
32.4 $
Step-by-step explanation:
25% off means he is paying 75% of the original price
Original price = 100%
75%=0.75=3/4
3/4 of 40 is 30
Apply 8% tax on amount of 30$ and add calculated value to 30$.
OR: you can think of 30 $ as 100%. You have to add 8% tax--. now you have 108%
108%=1.08
1.08*30=32.4
