The answer should be y= 8
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%.
Answer:
I think that it is 9 and 10 because when you simply the number 85 it would be 9.21 which is round by 9
