Answer:
Ethan paid $31.99 for the video game on sale.
Explanation:
Discount = 20% of $39.99
Discount = 0.20 * $39.99
Discount = $7.998 (rounded to the nearest cent)
Subtracting the discount from the original price:
Amount paid = $39.99 - $7.998
Amount paid = $31.992 (rounded to the nearest cent)
Therefore, Ethan paid $31.99 for the video game on sale.
