The supply function and demand function for the sale of a certain type of DVD player are given by ​S(p)=130e0.004p and ​D(p)=416
Ahat [919]

Answer:

p=$193.86 (assuming we are talking about dollars)

Step-by-step explanation:

In order to solve this problem, we must set each function equal to each other, so we end up with the following equation we must solve for p:

130e^{0.004p}=416e^{-0.002p}

So next, we divide both sides of the equation by 130 and by e^{-0.002p}

So we get:

\frac{e^{0.004p}}{e^{-0.002p}}=\frac{416}{130}

and we simplify, so we get:

e^{0.004p}e^{0.002p}=3.2

which can be further simplified to:

e^{0.006p}=3.2

and next, we take the natural logarithm to both sides, so we get:

0.006p=ln(3.2)

and finally we divide both sides of the equation by 0.006 so we get:

p=\frac{ln(3.2)}{0.006}

and simplify so we get our answer:

p=$193.86  (in the case that p is given in dollars)
