Calculus Question - How to find the marginal revenue?

The marginal revenue function is the differential of the total revenue function. |

For the total revenue function | | | |

| TR = | 500Q + 3Q^{2} | | |

where Q is the quantity produced, find the value of the marginal revenue (MR) when |

Q equals 71. |
| Give answer to nearest integer value. |

Can someone please show me how to answer this question? Thanks very much
