Answer:A. $209.53Step-by-step explanation:First, we have to take away 15% from the 850 dollar total so we can divide the remaining amount between the friends.15% can also be written as the fraction 0.15850 x 0.15 = 127.5Now, we subtract the money they put away from the total amount.850 - 127.5 = 722.5So, the three friends have $722.50 to split between each other.To figure out what amount everyone gets, we will first at together the total hours they worked.17.25 + 18.25 + 14.5 = 50Since the total hours is 50, we can divide the number of hours Shawn worked by 50 to find out what fraction of the total time he worked.14 ÷ 50 = 0.290.29 is the same as the percentage 29%. This means Shawn worked for 29% of the total time out of his friends.So, he gets 29% of the 722.50 dollars.0.29 x 722.5 = 209.525Round it up to 209.53Shawn gets $209.53
