The tax rate on a dollar would be .08% you have 4 dollars you have 32 cents tax 4 divided in to 32 is 8. So for each dollar you pay 8 cents.
Because the square has similar lengths, the equation would be
(7x-2)(7x-2)
We can use FOIL to solve this:
The area is 49x^2 - 28x + 4 in^2.
If the next digit, which in this case is in the tens place, is a 5 or above then we know to round up.
Your answer is 5,503,600.
Hope this helps!
54/2 or 27 should be the answer
