You work as a sales clerk at a fashion boutique. The store is having a 20 percent off everything sale. Additionally, your manage
lubasha [3.4K]

Your answer is D.


The jeans are 40% off (because you add 20% more).

And the original cost of the jeans is $30.


You could have done:

30 · 0.40 = 12  (Find 40% of $30, then subtract 30 by 40% of 30 to get the new sale price]

30 - 12 = 18


1 - 0.40 = 0.60  (You subtract 1 by 0.40 to get 0.60, which is the % of the original price that you have to pay)

30 · 0.60 = 18

Soon after taking an aspirin, a patient has absorbed 320 mg of the drug. after 3 hours, only 40 mg remain. find an exponential m
Anastaziya [24]
The equation will be of the form:
A(t)= A_{0} e^{rt}
where A is the amount after t hours, and r is the decay constant.
To find the value of r, we plug the given values into the equation, giving:
40=320e^{3r}
Rearranging and taking natural logs of both sides, we get:
ln\ 0.125=3r
r=\frac{ln\ 0.125}{3}=-0.693
The required model is:
A=A _{0} e^{-0.693t}
