Question

At a local school supply store, a highlighter costs $1.25, a ballpoint pen costs $0.80, and a spiral notebook costs $2.75. Explain how you can use the Commutative Property of Addition to find the total cost if three of each item are purchased!

Answer 1

Since the communative property shows you can add or multipy in any order, this means you can add all three of these in a different order and still get the same answer.....For example, you can do $1.25 + $0.80 + $2.75 or you can switch it around and do it in another way

Answer 2

The addition of all costs using commutative property will be $4.8.

What is the arithmetic operator?

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given,

Cost of one highlighter = $1.25

Cost of one ballpoint pen = $0.80

Cost of one spiral notebook = $2.75

The cumulative property states that the resultant of summation or multiplication does change by changing order.

Addition = 1.25 + 0.80 + 2.75

Total cost = $4.8.

Hence"The addition of all costs using commutative property will be $4.8".
