Hope this helps! :)
There is an explanation in the photo below, as well as some things to remember!
The commutative property states that you can move things around and it will still be equal. The best way to remember this is "commute" which kind of means to move around. 75000x = x75000, where x is the number of days. So, in this case, it would be 75000(5) = (5)75000 or 5 * 75000 = 75000 * 5.
A because you would take 0.8 and multiply it by 6.25 and get 5 so you would add the 5.5 to it
