First you need to make a multiplier:
1-(12/100) = 0.78

Then you multiply the price by 1.12 to get the final answer;
22 * 0.78 = 17.16

This means it cost $17.16 after the 12% sales tax.

Hope this helps! :)

The function A=A_oe^{-0.01155x} A = A o e − 0.01155 x models the amount in pounds of a particular radioactive material stored in

vivado [14]

They are essentially asking us to solve:

$357=900e^{-0.01155x} \implies\\ \frac{357}{900}=e^{-0.01155x} \implies\\ \ln{\frac{357}{900}}=-0.01155x \implies \\ x\approx 80.1$

Solving this equation for x tells us that it will take around 80.1 years for the materials in the vault to reduce to 357 pounds.
