Why the commutative and associative properties don't hold true for subtraction and division

Answers

The commutative and associative properties do not apply to both subtraction and division because once you move around your variables, you will produce different results, whereas in addition and multiplication, any change in position of numbers won't affect the result. The identity properties apply to them because once you add, subtract, multiply, or divide a certain number from any other number, you produce the same result, or, in other words, keep the number's "identity".

After 125% ,markup and a 10% discount, the price of a watch is $30.78 before tax, what was the whole price?

Answers

The 125% markup is $38.465 which I rounded it to $38.47 since it's money

To find the markup, you have to multiply 1.25 by 30.78 which you get $38.47 and then add it by $30.78 which you get $69.24

Then you multiply 10% or .10 by 69.24 which you get $6.92.

Finally, you just subtract $6.92 from $69.24 and you get the price of the watch which is $62.32
