Stephen Curry plays for the Golden State Warriors and have a 90% free throw shooting record. If he shot 20 free throws in a game, approximately how many did he miss?

Im pretty sure it’s is b 1.6 mi

So don't take my word i'm not exactly a mathematical person but i would assume a. because while selling the soap every month you increase in sells so you would by 11 percent. the you would get the factor 0.89 which if i had to guess would be the monthly profit over 11 probably wrong tho
