PROGRAMMING:Calculate taxi fare

Taxi pricing in n city is based on mileage, and the pricing standards are as follows:
*Within 3 km and 3 km, the starting price is $11 $$;
*After exceeding the starting kilometers, it will be charged according to $$2.4 $$per kilometer;
*After more than 10 km, an additional deadhead fee of $$0.96 $$per km will be charged.
For example:
*For a short journey of $$2 $$km, you only need to pay the fare of $$11 $;
*If the taxi cost is $$9 $$km, the fare is $$11 + (9-3) * 2.4 = 25.4 $$yuan;
*If you take a taxi for 13 km, the fare you need to pay is calculated as $$11 + 7 * 2.4 + (13-10) * (2.4 + 0.96) = 37.88 $$yuan, and the output is $$37.9 $$.
