I'm working through this problem, but I'm not getting an answer that is one of the multiple choices. Maybe there might be a typo, or maybe there is something I don't understand. But anyway here is my work:
First, we need to find the total hours worked, which if you add the four numbers, the total hours worked is 50.
Second, we know that they put 20% of the $1250 they earned in a savings account. 20% of $1250 is $250. So they have $1000 left over to split amongst themselves.
One way to continue from this point is to divide the $1000 by the 50 hours to see how much money someone would make per hour. So, a $1000 divided by 50 hours gives us $20 per hour.
In other words, for every hour that a person contributed to the landscaping business, you would earn $20.
Since Katie contributed 15.25 hours of work, she should get a total of:
15.25 x $20 = $305
Which unfortunately is not one of the answers. I don't think my calculations are off. But I hope that helps anyways!
