True statements:
a) x + y = y + x ⇒ commutative property of addition
b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication
d) (x + y) + z = x + (y + z) ⇒ associative property of addition
False statements:
c) x - y = y - x should be: x - y = - y + x
e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

How to calculate percentage of a number. Use the percentage formula: P% * X = Y</h3>
- Convert the problem to an equation using the percentage formula: P% * X = Y.
- P is 17%, X is 7.20, so the equation is 17% * 7.20 = Y.
- Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
Therefore, It costs $122.4 dollars before the increase.
