Order of operations: the rules of which calculation comes first in an expression.
They are: PEMDAS
<span><span>Do everything inside parentheses first: ()
</span><span>then do exponents: x2
</span><span>then do multiplies and divides from left to right
</span><span>lastly do the adds and subtracts from left to right</span></span>
It is 2x-1 that is your awnser
7.25 hour is better because multiply by eleven and its 79.75 which is higher than the on on the table
400. Just add a zero when you're dealing with tens
An=-5n+260
A40=60
So the Awnser is 60
(Hope this helped!!)
