Ms. Roth has made 200 headbands and is deciding what price to charge for them.
She knows that she will sell more if the price is lower. To estimate the number she can
expect to sell, she uses the function N defined as N(p) = 200 – 1.5p, where p is
the price in dollars.
Which choice describes a function, S(p), that models the total sales in dollars she can
expect?

Answer:

I THINK:

There will be 8 grams left after 36 minutes.

Step-by-step explanation:

A half-life is how long it takes for half of the amount to go away. in this case, we see that we have two half-life periods worth, which you can determine by dividing the total time by the half-life time.

36mins/16mins = 2 half lives.

now we can raise 1/2 to the power of how many half lives we have (2). then we multiply that by the amount in the sample.

(1/2)^2 * 36

1/4 * 36

8 grams
