The KEY is to understand the relationship between the dollar amount of the sales tax and the sales tax percentage.
To calculate the dollar amount of tax, you'd multiply the cost by the percentage.
So that $457.50 would be equal to cost x 7.5%. Now we have an algebra problem, 457.50 = Cost x 7.5%. To solve, we do the opposite of what's being done to cost now, which is multiplying by 7.5%. Well the opposite of multiplying is dividing, so we'd divide both sides by 7.5% (0.075 mathematically).
This gives us 457.50 / 0.075 = cost, making cost equal to $6100.

Let X = the price of the car, and remember that 7.5% = 0.075
.075 times X = 457.5
divide both side by .075
you get:
X = 457.5/.075 = 6100
The old car sold for $6100.

Tax = cost * tax rate
$457.50 = C * .07.5
C = 457.50/0.075
Cost = $6100
