It is False.
If a property is commutative in subtraction it means: x - y is the same as y - x.
For example 5 - 3 = 2, but 3 - 5 = -2 so subtraction is not commutative.
But 5 + 3 = 8 , is the same as 3 + 5 = 8.
Addition is Commutative, but Subtraction is not commutative.
So the statement that subtraction of whole numbers is commutative is False.
Y= 3/2x would be the answer.
$15 x .0725 = 1.0875 which we have to round to $1.09
Notice how I changed the 7.25% to a decimal .0725 by moving it back two places.
