X^2=19x+1
x^2-19x-1=0
-(-19)+(19^2-4(1)(-1))^(1/2))/(2*1)
(19+(361+4)^(1/2))/(2)
=(19+(365^(1/2))/2
=(19-(365^(1/2))/2

the sales tax for an item was $30.10 and it cost $430 before tax. find the sale tax rate. write your answer as a percentage.
timurjin [86]
To find a percentage of a number, multiply by the decimal form of that percentage(20%=0.20). So, take the cost, $430, and multiply by common state sales tax (7% for me)---430 x 0.07 = 30.10  The sale tax rate is 7%.
