Any fraction in between the two
I would say that the last one would be the most accurate.
The polynomial function is shown about between 10 and 15.
X= sales tax %
Step 1:
$240 * sales tax %= $12
240 * x= 12
240x=12
Divide both sides by 240
x= 0.05 (decimal of the %)
Convert to %:
Multiply decimal by 100 (or move decimal to the right two decimal places
=0.05 x 100
=5 %
The sales tax is 5%.
Hope this helps! :)
The scale factor for math numbers are the numbers you multiply to get an anwser for its factor.
Ex: factor of 2 is 2,4,6,8 and so on with each number
