8.61 would be 8.7 because you would use the 8 to round and if the number is larger then 5 then you raise the score if its lower then you lower the score
"5 or more raise the score 4 or less let it rest"
a good way to remember that
I think the answer would be 45x+20+45y. That is because Bess and Gina both earn $45 per week. We don't know how many weeks they worked for so that is x for Bess and y for Gina. But then Bess earns $20 bonus so you would add that to how much she already earned. They want to know the total amount of money they both earned together. So that would be 45x+20 (Bess) plus 45y (Gina).
Hope this helps!
