6.20 LAB: Driving costs - functions
Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('{:.2f}'.format(your_value))
Ex: If the input is:
20.0 3.1599
the output is:
1.58 7.90 63.20
Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles.
Ex: If the function is called with:
50 20.0 3.1599
the function returns:
7.89975
def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon)
Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles.

During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }arrow_forward3.
