The price, in dollars per units, that consumers are willing to pay for a popular high-end digital camera is given by the accompanying function, where x is in thousands of units. Complete parts (a) and (b). p(x) = 1570 - 135 In x a) What price corresponds to a demand of 390,000 units? How can the price that corresponds to a demand of 390,000 units be found? Select the correct choice below and fill in the answer box to complete your choice. (Simplify your answer.) A. Evaluate p( 390 ). O B. Solve = 1570 - 135 In x for x. The price that corresponds to a demand of 390,000 units is $ (Round to the nearest cent as needed.)Suppose that Po is invested in a savings account in which interest is compounded continuously at 7.1% per year. That is, the balance P grows at the rate given by the following equation. dP = 0.071P(t) dt (a)Find the function P(t) that satisfies the equation. Write it in terms of Po and 0.071.
