What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

Given that she earns 6% commission on the first $45,000 in sales and 8% on anything over that.

If Sally had $51,000 in sales this month

We have to determine her commission earnings this month

For the amount, she sold above $45,000

So, 51000 - 45000 = 6000

So her commission earning in this month as

⇒ (6/100)×45000 + (8/100)×6000

⇒ 2700 + 480

⇒ 3180.

Hence, her commission earning is $3180 this month.

To find the answer we must calculate her comission earnings for $45.000 and for the amount she sold above $45.000 (in our case, 51.000 - 45.000 = 6.000). So in total we have 6/100 * 45.000 + 8/100 * 6000 = 2700 + 480 = 3180.
