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?

$31.99

Step-by-step explanation:

39.99 * 0.2 = 7.9 rounded is 8

39.99 - 8 = 31.99

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)

30005

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
