Answer:
2.56
Explanation:
I went through the days, doing whatever operation it instructed to do. Monday, Multiply 2.21 by two. Tuesday, add .39 to 4.42, you're left with 4.81. Wednesday, subtract 1.76. You're left with 3.05. 4/5 of 3.05 is 2.44. Friday, add .12 to 2.44. His share is worth 2.56 at the end of the week. Hope this helps.
