A car service charges customers a flat fee per ride (which is higher during rush hour traffic) plus charges for each minute and each mile. Suppose that, in a certain metropolitan area during rush hour, the flat fee is $4, the cost per minute is $0.40, and the cost per mile is $1.20. Let x be the number of minutes and y the number of miles. At the end of a ride, the driver said that the passenger owed $10.00 and remarked that the number of minutes was two times the number of miles. Find the number of minutes and the number of miles for this trip. Whole numbers. Complete the equation that represents the total cost of the ride. 0.40x+ 1.20y +4 =10.00 (Do not include the $ symbol in your answer. Do not simplify. Use integers or decimals for any numbers in the equation.) Complete the equation that represents the relationship between the number of minutes and number of miles. =0 (Do not simplify.
