First, we determine the percentage increase for the tax.

Initial amount = 25×9 = 225 ⇒ The 9 signifies 9 lots of thousands representing the house's value.
New amount = 28×9 = 252

Tax increase = 252 - 225 = 27  
Percentage increase = (27÷225) ×100 = 12%

Therefore, the yearly rent should rise by 12%

Monthly rent is $60
Yearly rent = 60×12 = $720
With a 12% increase = 720×1.12 = 806.4 ⇒ Here, 1.12 is the multiplier derived from 100%+12%=112%=1.12

Monthly rent becomes 806.4÷12 = $67.20, resulting in an additional $7.20 each month.

The distance formula is
. In the ordered pairs (4, 6), the first number 4 represents the x-coordinate while 6 is the y-coordinate. In (7, -3), 7 is the x-coordinate and -3 is the y-coordinate. Substituting these coordinates results in
. Since subtracting a negative is equivalent to adding a positive, we now have
