Use systems of equations to work these applied problems. (See Examples 1-5.)
Lyft Rates Lyft charges customers a flat fee per ride (which is higherduring rush hour traffic) plus charges for each minute and each mile.(Data from: www.nyt.com.) Suppose that, in a certain metropolitan area during rush hour, the flat fee is $4, the cost per minute is $20, and the cost per mile is $1.40. Let x be the number of minutes and y thenumber of miles. At the end of a ride, the driver said that you owed $14 and remarked that the number of minutes was three times the number of miles. Find the number of minutes and the number of miles for thistrip.
