Well first to find out how much the cookies are on sale you do
2.80/7= 0.40

So on sale each cookie is 40 cents each, now to figure out the normal price add 75 cent to the sale price so:
0.40 + 0.75 = 1.15
So that gives us $1.15
So the normal price for the cookies is $1.15 and the sale price is $0.40 cents

A radioactive compound with mass of 260 grams decays at a rate of 3.8% per hour. Which equation represents how many grams of the
Dahasolnce [82]

The exponential equation that represents how many grams of the compound will remain after 8 hours is:

B: C=260(0.962)^8

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

A radioactive compound with mass of 260 grams decays at a rate of 3.8% per hour, hence the equation for the mass after t hours is given by:

A(t) = 260(1 - 0.038)^t

A(t) = 260(0.962)^t

After 8 hours, the amount is given by:

A(t) = 260(0.962)^8

Hence option B is correct.
