Ethan buys a video game on sale. If the video game usually costs $39.99, and it was on sale for 20% off, how much did Ethan pay?


  1. Answer
    Ethan will pay $31.99 with the discount.
    Step-by-step explanation:
    1. you need to set it up as a ratio (of course, you do not need to do this, but it is easier for me to do it this way)
    2. the ratio will look like this: 39.99/100% x/20%
    3. all we need to do from here is to cross multiply!
    4 39.99 x
    ———- = ———-
    100 20
    -price is on the top and percent on the bottom
    -you would now do 39.99 times 20
    -then divide by 100
    5. once you have 20% of 39.99, you need to subtract that answer from the total
    6. 39.99 – 7.998 = 31.992 (you need to round to the nearest hundredth)
