Answer:
12.5%
Step-by-step explanation:
The price increased from 800 to 900. So what is the PERCENTAGE INCREASE??
The increase is 900 - 800 = 100
To find this in terms of original, we need to divide 100 by 800 and multiply by 100 to get the "percentage". Let's do it:

So the increase is 12.5% and thus the general sales tax is 12.5%

Answer:
0.02493
Step-by-step explanation:
We are to Find :
P(p > 0.12) ;
This is equivalent to:
1 - P(p ≤ 0.12)
Using the relation :
1 - P((p - po) / (√(po(1 -po)) / n))
1 -P((Z ≤0.12 -0.09) / (√(0.09(1 -0.09)) / 350))
1 -P((Z≤0.03 / (√(0.09(0.91))/350))
1 - P((Z≤0.03 / 0.0152970))
1 - P((Z≤1.96116)
1 - 0.97507 (from Z probability calculator)
= 0.02493
