Which expression could be used to determine the cost of a $50 video game after a 20 percent discount?

Answer:
d
Step-by-step explanation:
to find a discount you would multiply 50(0.20) whatever amount you get you would subtract that from 50
this is the same as 50(0.80)
I’m pretty sure it’s d, because 50 (0.80) = 50 x 0.80 which equals 40 which is the 20% discount off of 50
