I believe Claire makes $24.50 and Brooklyn makes $14.50, so if you wanted to make Brooklyn walk an extra hour, she would have 24.00 adding the supply fee which is $5 which would make it $29.00.
Now i am going to try to actually solve it
8.50x15=127.5
9.50x5=47.5
9.50x13=123.5
this is so wrong i am so sorry, i just hope this helps you understand your question a bit more!
