Answer:
$1,444
Step by Step Explanation
You have to break down the different commission rates on the total:
$24550 is the total Amount of Sales subject to commissions, which are paid at different rates:
1. $8000 x 4% = $320
2. $10000 x 6% = $600
3. Add $8000 + $10000 = $18000 and subtract from the total sales to get the last number for the 8% commission calculation.
4. $24550-$18000 = $6550 x 8% = $524
5. Add the three amounts together to get the total commission
$320+$600+$524 = $1,444
The answer would be -1/2(X+3)
For this case we must find the solution of the following expression:
"the square root of 4 plus the square root of 5"
We have to:
the square root of 4 is represented as 
the square root of 5 is represented as
So, we have:
