The charge to rent a car is $80 per day plus 15 cents per mile driven. what is the cost to rent a car that is driven n days and 100 miles?

Hello there,

So if there were 100 miles driven and each mile is 15 cents, then that is a total of $15 added to the total amount of days they had the car which we can't figure out. 

Hope this helped! 

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
