Can somebody help solve this problems pleaseA radio manufacturing firm has fixed cost of \$25.000 cost and variable cost of \$75.80 per radio. The radio sells for \$119.95. Write an expression for the profit function and find the number of radios that must be sold to break even. If money is invested at 9%, what is the effective annual rate if the investment is compounded a) quarterly? b) monthly? c) daily? d) countinuously? |

Why are there three zeros in the fixed cost? Is it typed correctly? For the questions about interest rates, read this article. |

Re: CAN SOMEBODY HELP SOLVE THIS PROBLEMS PLEASEIf the zeros are correct and the fixed cost is just \$25.00, then you break even after the first radio because 119.95 - 25.000 - 75.80 = 19.15. Meaning you are making \$19.15 profit off the first radio sold. Now, assuming the fixed cost is supposed to be \$250.00, the formula becomes Because you can't sell .66 of a radio, round up to the nearest digit. So you need to sell 6 radios to start turning a profit. Total profit can be calculated with the function ************************************************** ************* ************************************************** ************* As for the second question, I could be wrong, but here it goes: Quarterly: Monthly: Daily: Countinuously: not sure how to do this one though You could do it with calculus though like The limit should also equal I believe, again, don't quote me on it though... |

That limit is 1-e^0.09, but is the formula correct? |
