Let C(x) be the function which calculates the total cost of making x skirts.
There is going to be a fixed constant, 250, to which we will add 15$ per x skirts.
So C(x)=250+15x
Answer: 250+15x
7978 years
Step-by-step explanation:
A = A02^(-t/hl)
where hl = half-life.
Dividing both sides by A0 and taking the logarithm, we get
ln(A/A0) = -(t/hl)ln2
or solving for t,
t= -(hl)ln(A/A0)/ln2
note that A/A0 = 0.38
t = -(5715 yrs)[ln(0.38)/ln2]
= 7978 years
