Hey!
The first step to solving this problem would be to multiply 469.82 by 0.085.
<em>New Equation :</em>
469.82 × 0.085 = ?
<em>Solution {New Equation Solved} :</em>
469.82 × 0.085 = 39.9347
Ignore the forty seven at the end of the solution. You're only going to need 39.93. Now we'll add 469.82 and 39.93. This is the sales tax plus the regular price. Which will then bring us to our total.
<em>New Equation :</em>
469.82 + 39.93 = ?
<em>Solution {New Equation Solved} :</em>
469.82 + 39.93 = 509.75
<em>So, 469.82 plus 8.5 sales tax is</em> 509.75.
Hope this helps!

Answer:
The rate of decrease is 8%
Step-by-step explanation:
we know that
The general equation for the radioactive decay can be written as:

where
a is the amount in kilograms after time t.
a_0 is the original amount of the substance or y-intercept of the function
r is the decay rate, written in decimals.
t is the time
In this problem we have

so

solve for r

I would start like this: which year was the seventh AMC 8??
the first was in 1985
The second: 1986
3: 1987
4: 1988
5: 1989
6: 1990
7: 1991
so seventh AMC 8 took place in 1991.
she was then 12, so we can subtract this age from 1991:
1991-12=1979
so she was born in 1979!
